8-bit Tri-state Universal Shift Register - National Semiconductor

This 8-bit TRI-STATE shift/storage Register MM54HC299 MM74HC299 utilizes advanced silicon-gate CMOS technology. Along with the low power consumption and high noise immunity of standard CMOS integrated circuits, it has the ability to drive 15 LS-TTL loads. This circuit also features operating speeds compara- ble to the equivalent low power Schottky device. The MM54HC299 MM74HC299 features multiplexed in- puts/outputs to achieve full 8-bit data handling in a single 20-pin package. Due to the large output drive capability and TRI-STATE feature, this device is ideally suited for interfac- ing with bus lines in a bus oriented system. By National Semiconductor Corporation
