8-BIT BIDIRECTIONAL UNIVERSAL SHIFT REGISTER WITH PARALLEL I/O High-Performance Silicon-Gate CMOS

The IN74HC299 is identical in pinout to the LS/ALS299. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.

The IN74HC299features a multiplexed parallel input/output data port to achieve full 8-bit handling in a 20 pin package. Due to the large output drive capability and the 3-state feature, this device is ideally suited for interface with bus lines in a busoriented system.

? Outputs Directly Interface to CMOS, NMOS, and TTL

? Operating Voltage Range: 2.0 to 6.0 V

? Low Input Current: 1.0 ?A

? High Noise Immunity Characteristic of CMOS Devices
