Product Overview

The 74HCT166D is a 8-bit parallel-in/serial out Shift Register features a serial data input (DS), eight parallel data inputs (D0 to D7) and a serial output (Q7). When the parallel enable input (PE\) is low, the data from D0 to D7 is loaded into the shift register on the next low-to-high transition of the clock input (CP). When PE\ is high, data enters the register serially at DS with each low-to-high transition of CP. When the clock enable input (CE\) is low data is shifted on the low-to-high transitions of CP. A high on CE\ disables the CP input. Inputs include clamp diodes which enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
  • Synchronous parallel-to-serial applications
  • Synchronous serial input for easy expansion
  • TTL Input level
  • Complies with JEDEC standard No. 7A
