DESCRIPTION The M74HCT75 is an high speed CMOS 4 BIT D TYPE LATCH fabricated with silicon gate C2MOS technology. It contains two groups of 2 bit latches controlled by an enable input (G1*2 or G3*4). These two latch groups can be used in different circuits. Each latch has Q and Q outputs (1Q - 4Q and 1Q - 4Q). The data applied to the data input is transferred to the Q and Q outputs when the enable input is taken high and the outputs will follow the data input as long as the enable input is kept high. When the
enable input is taken low, the information data applied to the data input is retained at the outputs. The M74HCT75 is designed to directly interface HSC2MOS systems with TTL and NMOS components. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

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