74AVC8T245
8-Bit Dual-Supply Translating
Transceiver with Configurable
Voltage Translation and 3-State Outputs
GENERAL DESCRIPTION
FEATURES
The 74AVC8T245 is an 8-bit, dual-supply bus
transceiver with configurable voltage translation. The
An and Bn are 8-bit data input-output ports, DIR is the
● VCCA Supply Voltage Range: 0.8V to 3.6V
● VCCB Supply Voltage Range: 0.8V to 3.6V
● Inputs Accept Voltages up to 3.6V
● +12mA/-12mA Output Current
�����
direction control input. OE is an output enable input
and VCCA and VCCB are dual supply pins. The supply
voltage of VCCA and VCCB can range from 0.8V to 3.6V,
making the device suitable for bidirectional translating
among any of the 0.8V, 1.2V, 1.5V, 1.8V, 2.5V and
● Data Rates:
380Mbps (≥ 1.8V to 3.3V Translation)
260Mbps (≥ 1.1V to 3.3V Translation)
260Mbps (≥ 1.1V to 2.5V Translation)
210Mbps (≥ 1.1V to 1.8V Translation)
150Mbps (≥ 1.1V to 1.5V Translation)
100Mbps (≥ 1.1V to 1.2V Translation)
● Outputs in High-Impedance State when VCCA or
�����
3.3V voltage nodes. The An, OE and DIR pins are
referenced to VCCA and Bn pins are referenced to VCCB
.
The direction control (DIR) input determines the
direction of the data flow. The DIR (active high) enables
data from An ports to Bn ports. The DIR (active low)
enables data from Bn ports to An ports. The output
VCCB = 0V
● -40℃ to +125℃ Operating Temperature Range
● Available in Green TQFN-5.5×3.5-24L and
TSSOP-24 Packages
�����
enable (OE) input, when high, disables both An and Bn
ports, so the buses are effectively isolated.

ABSOLUTE MAXIMUM RATINGS (1)
Input Transition Rise and Fall Rate, Δt/ΔV...... 10ns/V (MAX)
Supply Voltage Range, VCCA............................. -0.5V to 4.6V
Supply Voltage Range, VCCB............................. -0.5V to 4.6V
Input Voltage Range, VI (2) ................................ -0.5V to 4.6V
Operating Temperature Range..................... -40℃ to +125℃
OVERSTRESS CAUTION
(2)
Output Voltage Range, VO
1. Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods may
affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions sectionis not implied.
3-State Mode .................................................. -0.5V to 4.6V
High-State or Low-State
A ports ..............................-0.5V to MIN (4.6V, VCCA + 0.5V)
B ports ..............................-0.5V to MIN (4.6V, VCCB + 0.5V)
Output Current, IO
High-State or Low-State ..........................................±50mA
Input Clamp Current, IIK (VI < 0)...................................-50mA
Output Clamp Current, IOK (VO < 0)..............................-50mA

ESD Susceptibility
2. The input and output voltage ratings may be exceeded if the
input and output clamp current ratings are observed.
3. The performance capability of a high-performance integrated
circuit in conjunction with its thermal environment can create
junction temperatures which are detrimental to reliability.
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.
HBM.............................................................................8000V
CDM ............................................................................1000V
