Features, Applications

The a 6-bit register with a buffered common Enable This device is similar to the 'F174 but with common Enable rather than common Master Reset


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 Full TTL and CMOS compatible

Enable Input (Active LOW) Data Inputs Clock Pulse Input (Active Rising Edge) Outputs

The 'F378 consists of six edge-triggered D-type flip-flops with individual D inputs and Q inputs The Clock (CP) and Enable (E) inputs are common to all flip-flops When the E input is LOW new data is entered into the register on the LOW-to-HIGH transition of the CP input When the E input is HIGH the register will retain the present data independent of the CP input
