DESCRIPTION 74AHC374; 74AHCT374 The 74AHC/AHCT374 are high-speed Si-gate CMOS devices and are pin patible with low power Schottky TTL (LSTTL). They are specified in pliance with JEDEC standard No. 7A. The 74AHC/AHCT374 are octal D-type flip-flops featuring separate D-type inputs for each flip-flop and 3-state outputs for bus oriented applications. A clock (CP) and an output enable (OE) input are mon to all flip-flops. The 8 flip-flops will store the state of their individual D-inputs that meet the set-up and hold times requirements on the LOW-to-HIGH CP transition. When OE is LOW the contents of the 8 flip-flops are available at the outputs. When OE is HIGH, the outputs go to the high-impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops. The ‘374’ is functionally identical to the ‘534’, but has non-inverting outputs. TYPICAL SYMBOL t PHL/t PLH fmax CI CO CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in µW). PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; ∑ (CL × VCC2 × fo) = sum of outputs; CL = output load capacitance in p F; VCC = supply voltage in Volts. 2. The condition is VI = GND to VCC. PARAMETER propagation delay; CP to Qn maximum clock frequency input capacitance output capacitance power dissipation capacitance CL = 50 p F; f = 1 MHz; notes 1 and 2 CONDITIONS AHC CL = 15 p F; VCC = 5 V CL = 15 p F; VCC = 5 V VI = VCC or GND 3.5 50 3.0 4.0 10...
