General description

The 74HC299; 74HCT299 are high-speed Si-gate CMOS devices which are pin-compatible with Low-power Schottky TTL (LSTTL) devices. 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

■ Cascadable for n-bit word lengths

■ ESD protection:

◆ HBM JESD22-A114E exceeds 2000 V

◆ MM JESD22-A115-A exceeds 200 V

■ Specified from −40 °C to +85 °C and from −40 °C to +125 °C
