Synchronous Up/Down Counters With Output Registers And Multiplexed 3-State Outpu

These low-power Schottky LSI devices incorporate synchronous up/down Counters four-bit D-type Registers and quadruple two-line to one-line multiplexers with three state outputs in a single 20-pin package. The up/down Counters are programmable from the data inputs and feature enable P and enable T and a ripple-carry output for easy expansion. The Register Counter select input R/C, selects the Counter when low and the Register when high for the three-state outputs, QA, QB, QC, and QD. These outputs are rated at 12 and 24 milliamperes (54LS/74LS) for good bus driving performance. By Texas Instruments
