FEATURES
74LVC377
DESCRIPTION
• Wide supply voltage range of 1.2V to 3.6V
• Conforms to JEDEC standard 8-1A
• Inputs accept voltages up to 5.5V
• CMOS low power consumption
• Direct interface with TTL levels
• Output drive capability 50Ω transmission lines @ 85°C
The 74LVC377 is a low-voltage Si-gate CMOS device, superior to
most advanced CMOS compatible TTL families.
The 74LVC377 has eight edge-triggered , D-type flip-flops with
individual D inputs and Q outputs. A common clock (CP) input loads
all flip-flops simultaneously when the data enable E is LOW. The
state of each D input, one set-up time before the LOW-to-HIGH
clock transition, is transferred to the corresponding output (Qn) of
the flip-flop. The E input must be stable only one set-up time prior to
the LOW-to-HIGH transition for predictable operation.

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.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
