MC14076B_05 Datasheet, PDF (1/8 Pages) ON Semiconductor – 4-Bit D-Type Register with Three-State Outputs

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.
Features
• Three−State 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 Low−Power TTL Loads or One Low−Power
Schottky TTL Load Over the Rated Temperature Range
• Pb−Free Packages are Available*

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.

Plastic “P and D/DW” Packages: – 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
high−impedance circuit. For proper operation, V_in and V_out should be constrained
to the range V_SS v (V_in or V_out) v V_DD.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either V_SS or V_DD). Unused outputs must be left open.
