Description
These devices are positive edge triggered flip-flops. The difference between HD74HC374 and HD74HC534 is only
that the former is a true outputs and the latter is a false outputs. Data at the D inputs, meeting the setup and hold time
requirements, are transferred to the Q outputs on positive going transitions of the clock (CK) input. When a high logic
level is applied to the output control (OC) input, all outputs go to a high impedance state, regardless of what signals are
present at the other inputs and the state of the storage elements.
Features
• High Speed Operation: tpd (Clock to Q) = 18 ns typ (CL = 50 pF)
• High Output Current: Fanout of 15 LSTTL Loads
• Wide Operating Voltage: VCC = 2 to 6 V
• Low Input Current: 1 µA max
• Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
• Ordering Information
