74AVC8T245  
8-bit dual supply translating transceiver with configurable  
voltage translation; 3-state  
Rev. 02 — 28 April 2009  
Product data sheet  
1. General description  
The 74AVC8T245 is an 8-bit, dual supply transceiver that enables bidirectional level  
translation. It features two data input-output ports (An and Bn), a direction control input  
(DIR), a output enable input (OE) and dual supply pins (VCC(A) and VCC(B)). Both VCC(A)  
and VCC(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 An, OE and DIR are referenced to VCC(A) and pins Bn are  
referenced to VCC(B). A HIGH on DIR allows transmission from An to Bn and a LOW on  
DIR allows transmission from Bn to An. The output enable input (OE) can be used to  
disable the outputs so the buses are effectively isolated.  
The device is fully specified for partial power-down applications using IOFF. The IOFF  
circuitry disables the output, preventing any damaging backflow current through the  
device when it is powered down. In suspend mode when either VCC(A) or VCC(B) are at  
GND level, both An and Bn are in the high-impedance OFF-state.  
2. Features  
I Wide supply voltage range:  
N VCC(A): 0.8 V to 3.6 V  
N VCC(B): 0.8 V to 3.6 V  
I Complies with JEDEC standards:

N JESD8-11 (0.9 V to 1.65 V)  
N JESD8-7 (1.2 V to 1.95 V)  
N JESD8-5 (1.8 V to 2.7 V)  
N JESD8-B (2.7 V to 3.6 V)  
I ESD protection:  
N HBM JESD22-A114E Class 3B exceeds 8000 V  
N MM JESD22-A115-A exceeds 200 V  
N CDM JESD22-C101C exceeds 1000 V  
I Maximum data rates:  
N 380 Mbit/s (1.8 V to 3.3 V translation)  
N 260 Mbit/s (1.1 V to 3.3 V translation)  
N 260 Mbit/s (1.1 V to 2.5 V translation)  
N 210 Mbit/s (1.1 V to 1.8 V translation)  
N 150 Mbit/s (1.1 V to 1.5 V translation)  
N 100 Mbit/s (1.1 V to 1.2 V translation)
