HC4514
DESCRIPTION
The 74HC4514 and the 74HC4515 are high speed
CMOS 4-LINE TO 16-LINE DECODERS WITH
LATCHED INPUTS fabricated in silicon gate
2
C MOS technology. They have the same high
speed performance of LSTTL combined with true
CMOS low power consumption.
HC4515
A binary code stored in the four input latches (A to
D) provides a high level (HC4514) or a low level
(HC4515) at the selected one of sixteen outputs excluding the other fifteen outputs, when the inhibit
input (INHIBIT) is held low. When the inhibit input is
held high, all outputs are kept low level (HC4514) or
high level (HC4515), while the latch function is available. The data applied to the data inputs are transfered 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.

(*) 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 operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC
