Dual-bit, dual-supply voltage level translator/transceiver;

3-state

Rev. 10 — 4 November 2021

Product data sheet

1. General description

The 74AVC2T45 is a dual-bit, dual-supply transceiver that enables bidirectional level translation.

It features two data input-output ports (nA and nB), a direction control input (DIR) and dual-supply

pins (V_CC(A)and V_CC(B)). Both V_CC(A)and V_CC(B)can be supplied at any voltage between 0.8 V

and 3.6 V making the device suitable for translating between any of the low voltage nodes

(0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V). Pins nA and DIR are referenced to V_CC(A)and pins nB

are referenced to V_CC(B). A HIGH on DIR allows transmission from nA to nB and a LOW on DIR

allows transmission from nB to nA.

The device is fully specified for partial power-down applications using I_OFF. The I_OFFcircuitry

disables the output, preventing any damaging backflow current through the device when it is

powered down. In Suspend mode when either V_CC(A)or V_CC(B)are at GND level, both A and B are

in the high-impedance OFF-state.

2. Features and benefits

Suspend mode

Latch-up performance exceeds 100 mA per JESD 78 Class II

Inputs accept voltages up to 3.6 V

Low noise overshoot and undershoot < 10 % of V_CC

I_OFFcircuitry provides partial Power-down mode operation

Multiple package options

12.2. Bidirectional logic level-shifting application

Fig. 10 shows the 74AVC2T45 being used in a bidirectional logic level-shifting application. Since

the device does not have an output enable (OE) pin, the system designer should take precautions

to avoid bus contention between system-1 and system-2 when changing directions.

12.3. Power-up considerations

The device is designed such that no special power-up sequence is required other than GND being

applied first.

12.4. Enable times

The enable times for the 74AVC2T45 are calculated from the following formulas:

•

t_en(DIR to nA) = t_dis(DIR to nB) + t_pd(nB to nA)

t_en(DIR to nB) = t_dis(DIR to nA) + t_pd(nA to nB)

In a bidirectional application, these enable times provide the maximum delay from the time

the DIR bit is switched until an output is expected. For example, if the 74AVC2T45 initially is

transmitting from A to B, then the DIR bit is switched, the B port of the device must be disabled

before presenting it with an input. After the B port has been disabled, an input signal applied to it

appears on the corresponding A port after the specified propagation delay.

Definitions

Limiting values — Stress above one or more limiting values (as defined in

the Absolute Maximum Ratings System of IEC 60134) will cause permanent

damage to the device. Limiting values are stress ratings only and (proper)

operation of the device at these or any other conditions above those

given in the Recommended operating conditions section (if present) or the

Characteristics sections of this document is not warranted. Constant or

repeated exposure to limiting values will permanently and irreversibly affect

the quality and reliability of the device.
