SN54ALS191A, SN74ALS191A
SYNCHRONOUS 4-BIT UP/DOWN BINARY COUNTERS
SDAS210C – DECEMBER 1982 – REVISED JULY 1996
2
POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description (continued)
Two outputs are available to perform the cascading function: ripple clock and maximum/minimum count. The
latter output produces a high-level output pulse with a duration approximately equal to one complete cycle of
the clock while the count is minimum (0) counting down or maximum (15) counting up. The ripple-clock output
(RCO) produces a low-level output pulse under those same conditions, but only while the clock input is low. The
counter easily can be cascaded by feeding the ripple-clock output to the enable input of the succeeding counter
if parallel clocking is used, or to the clock input if parallel enabling is used. The maximum/minimum count
(MAX/MIN) output can be used to accomplish look ahead for high-speed operation.
The SN54ALS191A is characterized for operation over the full military temperature range of – 55
°C to 125°C.
The SN74ALS191A is characterized for operation from 0
°C to 70°C.
