FEATURES:
DESCRIPTION:
•
•
•
•
The IDT54/74FCT377T/AT/CT/DT are octal D flip-flops built
using an advanced dual metal CMOS technology. The IDT54/
74FCT377T/AT/CT/DT have eight edge-triggered, D-type flipflops with individual D inputs and O outputs. The common
buffered Clock (CP) input loads all flip-flops simultaneously
when the Clock Enable (CE) is LOW. The register is fully
edge-triggered. The state of each D input, one set-up time
before the LOW-to-HIGH clock transition, is transferred to the
corresponding flip-flop’s O output. The CE input must be
stable only one set-up time prior to the LOW-to-HIGH transition for predictable operation.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions
above those indicated in the operational sections of this specification is
not implied. Exposure to absolute maximum rating conditions for
extended periods may affect reliability. No terminal voltage may exceed
VCC by +0.5V unless otherwise noted.
2. Input and VCC terminals only.
3. Outputs and I/O terminals only.

6. IC = IQUIESCENT + IINPUTS + IDYNAMIC
