NTE4044BT 技术参数

NTE4044B & NTE4044BT

Integrated Circuit

CMOS, Quad NAND R/S Latch

Description:

The NTE4044B (16−Lead DIP) and NTE4044BT (SOIC−16) are R−S latch devices constructed

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

Each latch has an independent Q output and set and reset inputs. The Q outputs are gated through

three−state buffers having a common enable input. The outputs are enabled with a logical “1” or

high on the enable input; a logical “0” or low disconnects the latch from the Q outputs, resulting in

an open circuit at the Q outputs.

Features:

D Double Diode Input Protection

D Three−State Outputs with Common Enable

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