Parallel D Register with Enable
General Description
The ’F378 is a 6-bit register with a buffered common En-
able This device is similar to the ’F174 but with common
Enable rather than common Master Reset
Features
Y 6-bit high-speed parallel register
Y Positive edge-triggered D-type inputs
Y Fully buffered common clock and enable inputs
Y Input clamp diodes limit high-speed termination effects
Y Full TTL and CMOS compatible
