GENERAL DESCRIPTION

The 74HC/HCT299 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.

FEATURES

• Multiplexed inputs/outputs provide improved bit density

• Four operating modes:

– shift left

– shift right

– hold (store)

– load data

• Operates with output enable or at high-impedance OFF-state (Z)

• 3-state outputs drive bus lines directly

• Can be cascaded for n-bits word length

• Output capability: bus driver (parallel I/Os), standard (serial outputs)

• ICC category: MSI
