DESCRIPTION
The 74AHC/AHCT273 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.
The 74AHC/AHCT273 have eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs.
The common clock (CP) and master reset (MR) inputs load and reset (clear) all flip-flops simultaneously.
FEATURES
• Ideal buffer for MOS microcontroller or memory
• Common clock and master reset
• ESD protection:
