description (continued)
produces a high-level pulse while the count is maximum (9 or 15, with QA high). The high-level overflow
ripple-carry pulse can be used to enable successive cascaded stages. Transitions at ENP or ENT are allowed,
regardless of the level of CLK.
These counters feature a fully independent clock circuit. Changes at control inputs (ENP, ENT, or LOAD) that
modify the operating mode have no effect on the contents of the counter until clocking occurs. The function of
the counter (whether enabled, disabled, loading, or counting) is dictated solely by the conditions meeting the
stable setup and hold times.
The SN54ALS161B, SN54ALS162B, SN54ALS163B, SN54AS161, and SN54AS163 are characterized for
operation over the full military temperature range of – 55
°C to 125°C. The SN74ALS161B, SN74ALS163B,
SN74AS161, and SN74AS163 are characterized for operation from 0
°C to 70°C.
