54LS160A/DM74LS160A, 54LS162A/DM74LS162A
Synchronous Presettable BCD Decade Counters
General Description
The 'LS160 and 'LS162 are high speed synchronous decade
counters operating in the BCD (8421) sequence. They
are synchronously presettable for application in programmable
dividers and have two types of Count Enable inputs plus
a Terminal Count output for versatility in forming synchronous
multistage counters. The 'LS160 has an asynchronous
Master Reset input that overrides all other inputs and forces
the outputs LOW. The 'LS162 has a Synchronous Reset
input that overrides counting and parallel loading and allows
all outputs to be simultaneously reset on the rising edge of
the clock.
Features
Y Synchronous counting and loading
Y High speed synchronous expansion
Y Typical count rate of 35 MHz
Y Fully edge triggered
