74HC244; 74HCT244  
Octal buffer/line driver; 3-state  
Rev. 03 — 22 December 2005  
Product data sheet  
1. General description  
The 74HC244; 74HCT244 is a high-speed Si-gate CMOS device and is pin compatible  
with Low-power Schottky TTL (LSTTL).  
The 74HC244; 74HCT244 has octal non-inverting buffer/line drivers with 3-state outputs.  
The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on  
nOE causes the outputs to assume a high-impedance OFF-state. The 74HC244;  
74HCT244 is identical to the 74HC240; 74HCT240 but has non-inverting outputs.  
2. Features  
Octal bus interface  
Non-inverting 3-state outputs  
Complies with JEDEC standard no. 7A  
ESD protection:  
HBM EIA/JESD22-A114-C exceeds 2000 V  
MM EIA/JESD22-A115-A exceeds 200 V  
Multiple package options  
Specified from 40 °C to +85 °C and from 40 °C to +125 °C
