HEF4557B - 1-to-64 bit variable length shift register

Description

The HEF4557B is a static clocked serial shift register whose length may be programmed to be any number of bits between 1 and 64.

The number of bits selected is equal to the sum of the subscripts of the enabled length control inputs (L1, L2, L4, L8, L16, and L32) plus one.

Features

  • Fully static operation.
  • 5 V, 10 V, and 15 V parametric ratings.
  • Standardized symmetrical output characteristics.
  • Specified from 40 C to +85 C.
  • Complies with JEDEC standard JESD 13-B 3. Ordering information Table 1. Ordering information All types operate from 40 C to +85 C Type number Package Name.

HEF4557B 1-to-64 bit variable length shift register Rev. 6 — 18 November 2011 Product data sheet 1. General description The HEF4557B is a static clocked serial shift register whose length may be programmed to be any number of bits between 1 and 64. The number of bits selected is equal to the sum of the subscripts of the enabled length control inputs (L1, L2, L4, L8, L16, and L32) plus one. Serial data may be selected from the DA or DB data inputs with the A/B select input. This feature is useful for recirculation purposes. Information on DA or DB is shifted into the first register position and all the data in the register is shifted one position to the right on the LOW to HIGH transition of CP0 while CP1 is LOW or on the HIGH to LOW transition of CP1 while CP0 is HIGH.
