Product Details
__
8-Bit Bidirectional Universal Shift Register with Parallel I/O High- Performance Silicon-Gate CMOS
**The IN74HC299A isidenticalinpinoutto the LS/ALS299. The device inputs
are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.**
The IN74HC299A features a multiplexed parallel input/output data porttoachieve
full 8-bit handling ina 20 pin package. Due to the large output drive
capability andthe 3-state feature, this device is ideally suited for interface
with bus lines in a bus-oriented system.
Two Mode-Selectinputs and two OutputEnableinputs are used to choose the mode
of operation as listed in the Function Table. Synchronous parallel loading is
accomplished by taking both Mode Select lines, S1and S2, high. This places the
outputs in the high impedance state, which permits data applied to the data
port to be clocked into the register. Reading out of the register can be
accomplished when the outputs are enabled. The active-low asynchronous Reset
overrides all other inputs.
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range:2.0 to6.0 V
• Low InputCurrent:1.0 µA
• High Noise Immunity Characteristic of CMOS Devices
