DATASHEET

 

DESCRIPTION

The UT54ACS264 and the UT54ACTS264 are look-ahead generators designed specifically to perform a carry-anticipate across any number of n-bit counters, thus increasing system clock frequency. A carry enable CE, and carry outputs RCOA and RCOB are provided for n-bit cascading.

 

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

 

The devices are characterized over full military temperature range of -55¡C to +125¡C.
