MC14076B
4-Bit D-Type Register
with Three-State Outputs
The MC14076B 4–Bit Register consists of four D–type flip–flops
operating synchronously from a common clock. OR gated
output–disable inputs force the outputs into a high–impedance state
for use in bus organized systems. OR gated data–disable inputs cause
the Q outputs to be fed back to the D inputs of the flip–flops. Thus they
are inhibited from changing state while the clocking process remains
undisturbed. An asynchronous master root is provided to clear all four
flip–flops simultaneously independent of the clock or disable inputs.
• Three–State Outputs with Gated Control Lines
• Fully Independent Clock Allows Unrestricted Operation for the T wo
Modes: Parallel Load and Do Nothing
• Asynchronous Master Reset
• Four Bus Buffer Registers
• Supply Voltage Range = 3.0 Vdc to 18 Vdc
• Capable of Driving T wo Low–Power TTL Loads or One Low–Power
