High–Performance Silicon–Gate CMOS
The 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 l atch. The addressed l atch follows t he 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. In the one–of–eight decoding or demultiplexing
mode, the addressed output follows the state of Data In with all other outputs
in the LOW state. In the Reset mode all outputs are LOW and unaffected by
the address a nd data i nputs. W hen o perating t he H C259A a s an
addressable latch, changing more than one bit of the address could impose
a transient wrong address. Therefore, this should only be done while in the
memory mode.
• Output Drive Capability: 10 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2 to 6 V
• Low Input Current: 1 µA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
• Chip Complexity: 202 FETs or 50.5 Equivalent Gates

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high–impedance circuit. For proper operation, Vin and
V
out
should be constrained to the
range GND v (Vin or V
out
) v VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
