74HC245; 74HCT245  
Octal bus tranceiver; 3-state  
Rev. 03 — 31 January 2005  
Product data sheet  
1. General description  
The 74HC245; 74HCT245 is a high-speed Si-gate CMOS device and is pin compatible  
with Low-Power Schottky TTL (LSTTL).  
The 74HC245; 74HCT245 is an octal transceiver featuring non-inverting 3-state bus  
compatible outputs in both send and receive directions. The 74HC245; 74HCT245  
features an output enable input (OE) for easy cascading and a send/receive input (DIR)  
for direction control. OE controls the outputs so that the buses are effectively isolated.  
The 74HC245; 74HCT245 is similar to the 74HC640; 74HCT640 but has true  
(non-inverting) outputs.  
2. Features  
Octal bidirectional bus interface  
Non-inverting 3-state outputs  
Multiple package options  
Complies with JEDEC standard no. 7A  
ESD protection:  
HBM EIA/JESD22-A114-B exceeds 2000 V  
MM EIA/JESD22-A115-A exceeds 200 V  
Specified from 40 °C to +85 °C and from 40 °C to +125 °C
