DESCRIPTION The M74HC4515 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 low 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 high 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.

Input Capacitance Power Dissipation Capacitance (note 1)
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
