ZHCSMX9B –APRIL 2021 –REVISED MARCH 2022

具有施密特触发输入和三态输出的TXU0104-Q1 汽车类4 位定向电压电平转换

器

1 特性

2 应用

• 符合面向汽车应用的AEC-Q100 标准

• 采用具有可润湿侧翼的QFN (WBQA) 封装

• 完全可配置的双电源轨设计允许各个端口在1.1V 至

5.5V 范围内运行

• 在3.3V 至5.0V 范围内，支持最高200Mbps 的速

率

• 施密特触发输入可实现慢速和高噪声输入

• 带集成静态下拉电阻器的输入阻止通道流动

• 高驱动强度（在5V 时最高12mA）

• 低功耗

• 消除缓慢或嘈杂输入信号

• 驱动指示LED 或蜂鸣器

• 机械开关去抖

• 通用I/O 电平转换

• 推挽电平转换（UART、SPI、JTAG 等等）

3 说明

TXU0104-Q1 是一款 4 位双电源同相定向电压电平转

换器件。Ax 引脚以V_CCA逻辑电平为基准，OE 引脚可

以V_CCA或V_CCB逻辑电平为基准，Bx 引脚以 V_CCB逻

辑电平为基准。A 端口能够接受 1.1V 至 5.5V 的输入

电压，而 B 端口也可接受 1.1V 至 5.5V 的输入电压。

如果OE 相对于任一电源设为高电平，可能会发生从 A

到 B 或从 B 到 A 的定向数据传输。OE 设为低电平

时，所有输出引脚均处于高阻抗状态。请参阅器件功能

模式，简要了解控制逻辑的运行。

– 最大值3µA (25°C)

– 最大值6µA（-40°C 至125°C）

• V_CC隔离和V_CC断开(I_off-float) 特性

– 如果任何一个V_CC输入低于100mV 或已断开，

则所有输出均禁用且处于高阻抗状态

• I_off支持局部断电模式运行

• 带有V_CC(MIN)电路的控制逻辑(OE) 允许从端口A

或B 进行控制

• 引脚排列兼容TXB 系列电平转换器

• 在支持常见应用的其他型号中可用：TXU0204-

Q1、TXU0304-Q1

9 Detailed Description

9.1 Overview

The TXU0104-Q1 is a 4-bit translating transceiver that uses two individually configurable power-supply rails. The

device is operational with V_CCAand V_CCBsupplies as low as 1.1 V and as high as 5.5 V. Additionally, the device

can be operated with V_CCA= V_CCB. The A port is designed to track V_CCA, and the B port is designed to track

V_CCB

The TXU0104-Q1 device is designed for asynchronous communication between data buses, and transmits data

with fixed direction from the A bus to the B bus on some channels and from the B bus to the A bus on the

remaining channels. The output-enable input (OE) is used to disable the outputs so the buses are effectively

isolated. The output-enable pin of the TXU0104-Q1 (OE) can be referenced to either V_CCAor V_CCB. The OE pin

can be left floating or externally pulled down to ground to ensure the high-impedance state of the level shifter

outputs during power up or power down.

This device is fully specified for partial-power-down applications using the I_offcurrent. The I_offprotection circuitry

ensures that no excessive current is drawn from or sourced into an input or output while the device is powered

down.

The VCC isolation or VCC disconnect feature ensures that if either VCC is less than 100 mV or disconnected

with the complementary supply within recommended operating conditions, outputs are disabled and set to the

high-impedance state while the supply current is maintained. The I_off-floatcircuitry ensures that no excessive

current is drawn from or sourced into an input or output while the supply is floating.

Glitch-free power supply sequencing allows either supply rail to be powered on or off in any order while providing

robust power sequencing performance.

9.3 Feature Description

9.3.1 CMOS Schmitt-Trigger Inputs with Integrated Pulldowns

Standard CMOS inputs are high impedance and are typically modeled as a resistor in parallel with the input

capacitance given in the Electrical Characteristics. The worst case resistance is calculated with the maximum

input voltage, given in the Absolute Maximum Ratings, and the maximum input leakage current, given in the

Electrical Characteristics, using ohm's law (R = V ÷ I).

The Schmitt-trigger input architecture provides hysteresis as defined by ΔV_Tin the Electrical Characteristics,

which makes this device extremely tolerant to slow or noisy inputs. Driving the inputs slowly will increase

dynamic current consumption of the device. See Understanding Schmitt Triggers for additional information

regarding Schmitt-trigger inputs.

9.3.1.1 Inputs with Integrated Static Pull-Down Resistors

This device has 5 MΩ typical integrated weak pull-downs for each input. This feature allows all inputs to be left

floating without the concern for unstable outputs or increased current consumption. This also helps to reduce

external component count for applications where not all channels are used or need to be fixed low. If an external

pull-up is required, it should be no larger than 1 MΩto avoid contention with the 5 MΩinternal pull-down.

9.3.2 Control Logic (OE) with V_CC(MIN)Circuitry

The output-enable input (OE) is used to disable the outputs so the buses are effectively isolated. The output-

enable pin of the TXU0x04-Q1 has V_CC(MIN)circuitry, which allows the OE pin to operate with the lower supply

voltage. The Over-Voltage Tolerant Inputs feature allows the OE pin to operate with the higher supply voltage.

This combination means that the enable pin can be referenced to either V_CCAor V_CCBsupply. Multiple

permutations of each device are possible since the controller can be placed on either the A or B port and can still

control the enable pin.

9.3.3 Balanced High-Drive CMOS Push-Pull Outputs

A balanced output allows the device to sink and source similar currents. The high drive capability of this device

creates fast edges into light loads, so routing and load conditions should be considered to prevent ringing.

Additionally, the outputs of this device are capable of driving larger currents than the device can sustain without

being damaged. Absolute Maximum Ratings defines the electrical and thermal limits that must be followed at all

times.

9.3.4 Partial Power Down (I_off)

The inputs and outputs for this device enter a high-impedance state when the device is powered down, inhibiting

current backflow into the device. The I_offin the Electrical Characteristics specifies the maximum leakage into or

out of any input or output pin on the device.

9.3.5 VCC Isolation and V_CCDisconnect

The outputs for this device are disabled and enter a high-impedance state when either supply is <100 mV or left

floating (disconnected), with the complementary supply within recommended operating conditions. It is

recommended that the inputs are kept low before floating (disconnecting) either supply.

The I_{CCx(floating)}in the Electrical Characteristics specifies the maximum supply current. The I_off(float)in the

Electrical Characteristics specifies the maximum leakage into or out of any input or output pin on the device.

9.3.6 Over-Voltage Tolerant Inputs

Input signals to this device can be driven above the supply voltage so long as they remain below the maximum

input voltage value specified in the Recommended Operating Conditions.

9.3.7 Glitch-Free Power Supply Sequencing

Either supply rail may be powered on or off in any order without producing a glitch on the inputs or outputs (that

is, where the output erroneously transitions to VCC when it should be held low or vice versa). Glitches of this

nature can be misinterpreted by a peripheral as a valid data bit, which could trigger a false device reset of the

peripheral, a false device configuration of the peripheral, or even a false data initialization by the peripheral.

12 Layout

12.1 Layout Guidelines

To ensure reliability of the device, it is recommended to follow common printed-circuit board layout guidelines:

• Use bypass capacitors on the power supply pins and place them as close to the device as possible. A 0.1 µF

capacitor is recommended, but transient performance can be improved by having 1 µF and 0.1 µF capacitors

in parallel as bypass capacitors.

• The high drive capability of this device creates fast edges into light loads, so routing and load conditions

should be considered to prevent ringing.
