MC74HCT259A D

MC74HCT259A
8-Bit Addressable Latch
1-of-8 Decoder with LSTTL
Inputs
High−Performance Silicon−Gate CMOS
The MC74HCT259A is identical in pinout to the LS259. The device
inputs are compatible with standard CMOS and LSTTL outputs.
The HCT259A 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. 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 and data
inputs. When operating the HCT259A as 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.

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
Vout should be constrained to the
range GND v (Vin or Vout) 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.
