74HC244; 74HCT244  
Octal buffer/line driver; 3-state  
Rev. 4 — 24 September 2012  
Product data sheet  
1. General description  
The 74HC244; 74HCT244 is an 8-bit buffer/line driver with 3-state outputs. The device  
can be used as two 4-bit buffers or one 8-bit buffer. The device features two output  
enables (1OE and 2OE), each controlling four of the 3-state outputs. A HIGH on nOE  
causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes  
that enable the use of current limiting resistors to interface inputs to voltages in excess of  
VCC  
.
2. Features and benefits  
Input levels:  
For 74HC244: CMOS level  
For 74HCT244: TTL level  
Octal bus interface  
Non-inverting 3-state outputs  
Complies with JEDEC standard no. 7 A  
ESD protection:  
HBM JESD22-A114F exceeds 2000 V  
MM JESD22-A115-A exceeds 200 V  
Multiple package options  
Specified from 40 C to +85 C and 40 C to +125 C
