DESCRIPTION

The UT54ACS264 and the UT54ACTS264 are look-ahead gen-

eratorsdesignedspecificallytoperformacarry-anticipateacross

any number of n-bit counters, thus increasing system clock fre-

quency. AcarryenableCE, andcarryoutputsRCOAandRCOB

are provided for n-bit cascading.

V_DD

Use the counter with either active-high-carry or active-low-car-

ry counters. For active-high-carry counters, CE is active high,

the A set of inputs and output RCOA are used. The B set of

inputs are connected to a low logic level. For active-low-carry

counters, CE is active low, the B set of inputs and output RCOB

are used. The A set of inputs are connected to a high logic level.

V_SS

The devices are characterized over full military temperature

range of -55°C to +125°C.
