DESCRIPTION
The M74HC4514 is an high speed CMOS 4 LINE
TO 16 LINE SEGMENT DECODER WITH
LATCHED INPUTS fabricated with silicon gate
C2MOS technology.
A binary code stored in the four input latches (A to
D) provides a high level at the selected one of
sixteen outputs excluding the other fifteen outputs,
when the inhibit input (INHIBIT) is held low. When
the inhibit input (INHIBIT) is held high, all outputs
are kept low level, while the latch function is

available. The data applied to the data inputs are
transferred to the Q outputs of latches when the
strobe input is held high. When the strobe input is
taken low, the information data applied to the data
input at a time is retained at the output of the
latches.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC
