MC14076B
4-Bit D-Type Register
with Three-State Outputs
The MC14076B 4âBit Register consists of four Dâtype flipâflops
operating synchronously from a common clock. OR gated
outputâdisable inputs force the outputs into a highâimpedance state
for use in bus organized systems. OR gated dataâdisable inputs cause
the Q outputs to be fed back to the D inputs of the flipâflops. Thus they
are inhibited from changing state while the clocking process remains
undisturbed. An asynchronous master root is provided to clear all four
flipâflops simultaneously independent of the clock or disable inputs.
⢠ThreeâState Outputs with Gated Control Lines
⢠Fully Independent Clock Allows Unrestricted Operation for the Two
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 Two LowâPower TTL Loads or One LowâPower
Schottky TTL Load Over the Rated Temperature Range

1. Maximum Ratings are those values beyond which damage to the device
may occur.
2. Temperature Derating:
Plastic âP and D/DWâ Packages: â 7.0 mW/_C From 65_C To 125_C
This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
v v highâimpedance circuit. For proper operation, Vin and Vout should be constrained
to the range VSS (Vin or Vout) VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either VSS or VDD). Unused outputs must be left open.
