M54HCT162 SYNCHRONOUS PRESETTABLE 4-BIT COUNTER

M54/74HCT160 Decade, Asynchronous Clear M54/74HCT161 Binary, Asynchronous Clear M54/74HCT162 Decade, Synchronous Clear M54/74HCT163 Binary, Synchronous Clear The M54/74HCT160, 161, 162 and 163 are high speed CMOS SYNCHRONOUS PRESETTABLE COUNTERS fabricated with silicon gate C2MOS technology. They have the same high speed operation similar to equivalent LSTTL.

Features

161/163 are 4 bit binary counters. The CLOCK input is active on the rising edge. Both LOAD and CLEAR inputs are active Low. Presetting of all four IC’s is synchronous on the rising edge of the CLOCK. The function on the M54/74HCT162/163 is synchronous to CLOCK, while the M54/74HCT160/161 counters are cleared asynchronously. Two enable inputs (TE and PE) and CARRY output are provided to enable easycascading of counters, which facilities easy implementation of N-bit counters without using external gates. This integrated circuit has input and output characteristics that are fully compatible with .
