74HC74; 74HCT74  
Dual D-type flip-flop with set and reset; positive edge-trigger  
Rev. 8 — 9 February 2023  
Product data sheet  
1. General description  
The 74HC74 and 74HCT74 are dual positive edge triggered D-type flip-flop. They have individual  
data (nD), clock (nCP), set (nSD) and reset (nRD) inputs, and complementary nQ and nQ outputs.  
Data at the nD-input, that meets the set-up and hold time requirements on the LOW-to-HIGH clock  
transition, is stored in the flip-flop and appears at the nQ output. Schmitt-trigger action in the clock  
input, makes the circuit highly tolerant to slower clock rise and fall times. Inputs include clamp  
diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of  
VCC  
.
2. Features and benefits  
Wide supply voltage range from 2.0 to 6.0 V  
CMOS low power dissipation  
High noise immunity  
Input levels:  
For 74HC74: CMOS level  
For 74HCT74: TTL level  
Symmetrical output impedance  
High noise immunity  
Balanced propagation delays  
Latch-up performance exceeds 100 mA per JESD 78 Class II Level B  
Complies with JEDEC standards:  
JESD8C (2.7 V to 3.6 V)  
JESD7A (2.0 V to 6.0 V)  
ESD protection:  
HBM JESD22-A114F exceeds 2000 V  
MM JESD22-A115-A exceeds 200 V  
Multiple package options  
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
