74LS390 Product details

Description

Each of these monolithic circuits contains eight masterslave flip-flops and additional gating to implement two individual four-bit counters in a single package.

Features

s Dual version of the popular DM74LS90 s DM74LS390individual clocks for A and B flip-flops provide dual ÷ 2 and ÷ 5 counters s Direct clear for each 4-bit counter s Dual 4-bit version can significantly improve system densities by reducing counter package count by 50% s Typical maximum count frequency35 MHz s Buffered outputs reduce possibility of collector commutation Ordering Code: Order Number DM74LS390M DM74LS390N Package Number M16A N16E Package.
