Octal D-type flip-flop; positive edge-trigger (3-State)
FEATURES
DESCRIPTION
• Wide operating voltage: 1.0 to 5.5V
• Optimized for Low Voltage applications: 1.0 to 3.6V
• Accepts TTL input levels between VCC = 2.7V and VCC = 3.6V
• Typical VOLP (output ground bounce) 0.8V @ VCC = 3.3V,
The 74LV374 is a low-voltage Si-gate CMOS device and is pin and
function compatible with 74HC/HCT374.
The 74LV374 is an octal D-type flip–flop 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
common to all flip-flops.
Tamb = 25°C
• Typical VOHV (output VOH undershoot) 2V @ VCC = 3.3V,
The eight 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.
Tamb = 25°C
• Common 3-State output enable input
• Output capability: bus driver
• ICC category: MSI
When OE is LOW, the contents of the eight flip-flops is 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.

Notes 1 and 2
NOTES:
1. CPD is used to determine the dynamic power dissipation (PD in µW)
PD = CPD VCC2 x fi (CL VCC2 fo) where:
fi = input frequency in MHz; CL = output load capacity in pF;
fo = output frequency in MHz; VCC = supply voltage in V;
(CL VCC2 fo) = sum of the outputs.
2. The condition is VI = GND to VCC
