High Voltage Types (20V Rating)

Features

Description

• Low Symmetrical Output Resistance, Typically 100Ω

CD4541B programmable timer consists of a 16-stage binary

counter, an oscillator that is controlled by external R-C compo-

nents (2 resistors and a capacitor), an automatic power-on

reset circuit, and output control logic. The counter increments

on positive-edge clock transitions and can also be reset via the

MASTER RESET input.

• External Clock (Applied to Pin 3) can be Used Instead

The output from this timer is the Q or Q output from the 8th,

10th, 13th, or 16th counter stage. The desired stage is chosen

using time-select inputs A and B (see Frequency Select Table).

The output is available in either of two modes selectable via the

MODE input, pin 10 (see Truth Table). When this MODE input is

a logic “1”, the output will be a continuous square wave having

Timing is initialized by setting the AUTO RESET input (pin 5) to

logic “0” and turning power on. If pin 5 is set to logic “1”, the

AUTO RESET circuit is disabled and counting will not start until

after a positive MASTER RESET pulse is applied and returns

to a low level. The AUTO RESET consumes an appreciable

amount of power and should not be used if low-power operation
