74LVC245A; 74LVCH245A  
Octal bus transceiver; 3-state  
Rev. 05 — 25 August 2009  
Product data sheet  
1. General description  
The 74LVC245A; 74LVCH245A are 8-bit transceivers featuring non-inverting 3-state bus  
compatible outputs in both send and receive directions. The device features an output  
enable (OE) input for easy cascading and a send/receive (DIR) input for direction control.  
OE controls the outputs so that the buses are effectively isolated.  
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be  
applied to the outputs. These features allow the use of these devices in mixed  
3.3 V and 5 V applications.  
The 74LVCH245A bus hold on data inputs eliminates the need for external pull-up  
resistors to hold unused inputs.  
2. Features  
I 5 V tolerant inputs/outputs for interfacing with 5 V logic  
I Wide supply voltage range from 1.2 V to 3.6 V  
I CMOS low-power consumption  
I Direct interface with TTL levels  
I Inputs accept voltages up to 5.5 V  
I High-impedance when VCC = 0 V  
I Bushold on all data inputs (74LVCH245A only)  
I Complies with JEDEC standard no. 8-1A  
I ESD protection:  
N HBM JESD22-A114E exceeds 2000 V  
N MM JESD22-A115-A exceeds 200 V  
I Specified from 40 °C to +85 °C and 40 °C to +125 °C
