74HC244; 74HCT244  
Octal buffer/line driver; 3-state  
Rev. 7 — 27 July 2021  
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  
Wide supply voltage range from 2.0 to 6.0 V  
CMOS low power dissipation  
High noise immunity  
Latch-up performance exceeds 100 mA per JESD 78 Class II Level B  
Input levels:  
For 74HC244: CMOS level  
For 74HCT244: TTL level  
Octal bus interface  
Non-inverting 3-state outputs  
Complies with JEDEC standards:  
JESD8C (2.7 V to 3.6 V)  
JESD7A (2.0 V to 6.0 V)  
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
