register utilizes advancedsilicon-gate CMOS technology Along with the low powerconsumption and high noise immunity of standard CMOSintegrated circuits it has the ability to drive15LS-TTLloads This circuit also features operating speeds compara-ble to the equivalent low power Schottky deviceThe MM54HC299 MM74HC299features multiplexed in-puts outputs to achieve full8-bit data handling in a single20-pin package Due to the large output drive capability andTRI-STATE feature this device is ideally suited for interfac-ing with bus lines in a bus oriented systemTwo function select inputs and two output control inputs areused to choose the mode of operation as listed in the func-tion table Synchronous parallel loading is accomplished bytaking both function select lines S0and S1high This placesthe TRI-STATE outputs in a high impedance state whichpermits data applied to the input output lines to be clockedinto the register Reading out of the register can be donewhile the outputs are enabled in any mode A direct overrid-ing CLEAR input is provided to clear the register whetherthe outputs are enabled or disabledThe54HC 74HC logic family is functionally as well as pinoutcompatible
