A binary code applied to the four inputs (A to D)
provides a low level at the selected one of sixteen
outputs excluding the other fifteen outputs, when
both the strobe inputs, G1 and G2, are held low.
When either strobe input is held high, the
decoding function is inhibited to keep all outputs
high. The strobe function makes it easy to expand
the decoding lines through cascading, and
simplifies the design of address decoding circuits
in memory control systems.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

pF
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
TEST CIRCUIT
CL = 50pF or equivalent (includes jig and probe capacitance)
RT = ZOUT of pulse generator (typically 50Ω)
