HEF4015B
Dual 4-bit static shift register
Rev. 8 — 21 November 2011
Product data sheet
1. General description
The HEF4015B is a dual edge-triggered 4-bit static shift register (serial-to-parallel
converter). Each shift register has a serial data input (D), a clock input (CP), four fully
buffered parallel outputs (Q0 to Q3) and an overriding asynchronous master reset input
(MR). Information present on D is shifted to 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 CP. A
HIGH on MR clears the register and forces Q0 to Q3 to LOW, independent of CP and D.
The clock input’s Schmitt trigger action makes the input highly tolerant of slower clock rise
and fall times.
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS
(usually ground). Unused inputs must be connected to VDD, VSS, or another input.
