MC74HCT259A
8-Bit Addressable Latch
1-of-8 Decoder with LSTTL
Inputs
HighPerformance SiliconGate 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 nonaddressed 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 oneofeight
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.
