NTE4020BT 技术参数

NTE4020B & NTE4020BT

Integrated Circuit

CMOS, 14−Bit Binary Counter

Description:

The NTE4020B (16−Lead DIP) and NTE4020BT (SOIC−16) are 14−stage binary counter devices

constructed with MOS P−Channel and N−Channel enhancement mode devices in a single monolithic

structure. These devices are designed with an input wave shaping circuit and 14 stages of ripple−

carry binary counter. The device advances the count on the negative−going edge of the clock pulse.

Applications include time delay circuits, counter controls, and frequency−dividing circuits.

Features:

D Fully Static Operation

D Diode Protection on All Inputs

D Supply Voltage Range: 3Vdc to 18Vdc

D Capable of Driving Two Low−Power TTL Loads or One Low−Power Schottky TTL Load Over

the Rated Temperature Range

D Buffered Outputs Available from Stages 1 and 4 Through 14

D Common Reset Line
