MC54HC259A

8-Bit Addressable Latch 1-of-8 Decoder

MC54HC259AJ

8-Bit Addressable Latch 1-of-8 Decoder;

High–Performance Silicon–Gate CMOSThe MC54/74HC259A is identical in pinout to the LS259. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The HC259A has four modes of operation as shown in the mode selection table. In the addressable latch mode, the data on Data In is written into the addressed latch. The addressed latch follows the data input with all non–addressed latches remaining in their previous states. In the memory mode, all latches remain in their previous state and are unaffected by the Data or Address inputs.? Output Drive Capability: 10 LSTTL Loads\n? Outputs Directly Interface to CMOS, NMOS, and TTL\n? Operating Voltage Range: 2 to 6 V\n? Low Input Current: 1 μA\n? High Noise Immunity Characteristic of CMOS Devices\n? In Compliance with the Requirements Defined by JEDEC Standard No. 7A\n? Chip Complexity: 202 FETs or 50.5 Equivalent Gates
