Philips Semiconductors
Octal buffer/line driver (3-State)
Product specification
74ABT244
FEATURES
• Octal bus interface
• 3-State buffers
• Output capability: +64mA/–32mA
• Latch-up protection exceeds 500mA per Jedec Std 17
• ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200 V per Machine Model

DESCRIPTION
The 74ABT244 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT244 device is an octal buffer that is ideal for driving bus
lines. The device features two Output Enables (1OE, 2OE), each
controlling four of the 3-State outputs.
