LS7055 Overview
The LS7055/LS7056 is a MOS synchronous 6 decade Up/Down counter. The circuit includes storages and parators, zero detect, automatic presetting and resetting, output latches, multiplexed output BCD and seven segment data. Thumbwheel switches can be used to provide BCD data to the storage networks in the circuit.
