Product specification
74F378
Hex D flip-flop with enable
2
1989 Oct 05
853–0067 97804
FEATURES
6-bit high-speed parallel register
Positive edge-triggered D-type inputs
Fully buffered common Clock and Enable inputs
Input clamp diodes limit high speed termination effects
Fully TTL and CMOS compatible
DESCRIPTION
The 74F378 has six edge-triggered D-type flip-flops with individual
D inputs and Q outputs. The common buffered Clock (CP) input
loads all flip-flops simultaneously when the Enable (E) input is Low.
The register is fully edge-triggered. The state of each D input, one
setup time before the Low-to-High clock transition is transformed to
the corresponding flop-flop’s Q output. The E input must be stable
one setup time prior to the Low-to-High clock transition for
predictable operation.
