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
