Hef 4516 BT

This document provides a data sheet for the HEF4516B binary up/down counter integrated circuit. The HEF4516B is an edge-triggered 4-bit synchronous up/down counter with inputs for clock, count enable, parallel load, parallel data, and up/down control. It has outputs for the 4 bit counter value and a terminal count signal. The data sheet specifies the pinout, logic diagram, truth table, and timing characteristics of the device.

DESCRIPTION Information on P0 to P3 is loaded into the counter while PL


is HIGH, independent of all other input conditions except
The HEF4516B is an edge-triggered synchronous
MR which must be LOW. When PL and CE are LOW, the
up/down 4-bit binary counter with a clock input (CP), an
counter changes on the LOW to HIGH transition of CP.
up/down count control input (UP/DN), an active LOW
Input UP/DN determines the direction of the count, HIGH
count enable input (CE), an asynchronous active HIGH
for counting up, LOW for counting down. When counting
parallel load input (PL), four parallel inputs (P0 to P3), four
up, TC is LOW when O0 and O3 are HIGH and CE is LOW.
parallel outputs (O0 to O3), an active LOW terminal count
When counting down, TC is LOW when O0 to O3 and
output (TC), and an overriding asynchronous master reset
CE are LOW. A HIGH on MR resets the counter (O0 to
input (MR).
O3 = LOW) independent of all other input conditions.

Notes
1. H = HIGH state (the more positive voltage)
L = LOW state (the less positive voltage)
X = state is immaterial
