74ABT244
74ABT244 is Octal buffer/line driver manufactured by NXP Semiconductors.
FEATURES
- Octal bus interface
- 3-State buffers
- Output capability: +64m A/- 32m A
- Latch-up protection exceeds 500m A 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 Bi CMOS device bines 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.
- Power-up 3-State
- Live insertion capacity
- Inputs are disabled during 3-State mode
