description
The ’HC148 feature priority decoding of the inputs
to ensure that only the highest-order data line is
encoded. These devices encode eight data lines
to 3-line (4-2-1) binary (octal). Cascading circuitry
(enable input EI and enable output EO) has been
provided to allow octal expansion without the
need for external circuitry. Data inputs and outputs
are active at the low logic level.
The SN54HC148 is characterized for operation
over the full military temperature range of –55
°C
to 125
°C. The SN74HC148 is characterized for
operation from –40
°C to 85°C.
