High-Speed CMOS Logic

Presettable Counters

February 1998 - Revised October 2003

Two count enables, PE and TE, in each counter are

provided for n-bit cascading. In all counters reset action

occurs regardless of the level of the SPE, PE and TE inputs

(and the clock input, CP, in the ’HC161 and ’HCT161

types).

Synchronous Reset

If a decade counter is preset to an illegal state or assumes

an illegal state when power is applied, it will return to the

normal sequence in one count as shown in state diagram.

• Synchronous Counting and Loading

• Two Count Enable Inputs for n-Bit Cascading

• Look-Ahead Carry for High-Speed Counting

The look-ahead carry feature simplifies serial cascading of

the counters. Both count enable inputs (PE and TE) must

be high to count. The TE input is gated with the Q outputs

of all four stages so that at the maximum count the terminal

count (TC) output goes high for one clock period. This TC

pulse is used to enable the next cascaded stage.

Description

The ’HC161, ’HCT161, ’HC163, and ’HCT163 are

presettable synchronous counters that feature look-ahead

carry logic for use in high-speed counting applications. The

’HC161 and ’HCT161 are asynchronous reset decade and

binary counters, respectively; the ’HC163 and ’HCT163

devices are decade and binary counters, respectively, that

are reset synchronously with the clock. Counting and

parallel presetting are both accomplished synchronously

with the negative-to-positive transition of the clock.

A low level on the synchronous parallel enable input, SPE,

disables counting operation and allows data at the P0 to P3

inputs to be loaded into the counter (provided that the

setup and hold requirements for SPE are met).

All counters are reset with a low level on the Master Reset

input, MR. In the ’HC163 and ’HCT163 counters

(synchronous reset types), the requirements for setup and

hold time with respect to the clock must be met.

NOTE: When ordering, use the entire part number. The suffix 96

denotes tape and reel. The suffix T denotes a small-quantity reel of

250.

CAUTION: These devices are sensitive to electrostatic discharge. Users should follow proper IC Handling Procedures.
