DESCRIPTION
The M54HC148 is an high speed CMOS 8 TO 3
LINE
PRIORITY
ENCODER
fabricated
with
silicon gate C2MOS technology.
The M54HC148 encodes eight data lines to
three-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
are active at the low logic level.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
