Product specification
74AHC164; 74AHCT164
FEATURES
• ESD protection: HBM EIA/JESD22-A114-A exceeds 2000 V MM EIA/JESD22-A115-A exceeds 200 V CDM EIA/JESD22-C101 exceeds 1000 V
• Balanced propagation delays • All inputs have Schmitt-trigger actions • Inputs accept voltages higher than VCC • For AHC only: operates with CMOS input levels • For AHCT only: operates with TTL input levels • Specified from −40 to +85 °C and from −40 to +125 °C.
DESCRIPTION
The 74AHC/AHCT164 shift registers are high-speed silicon-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/AHCT164 input signals are 8-bit serial through one of two inputs (Dsa or Dsb); .
