CMOS 4-BIT D-TYPE REGISTERS

DESCRIPTION

The UTC UCD4076 are 4-bit registers consisting of D-type

flip-flops that feature 3-state outputs. Data Disable inputs are

provided to control the entry of data into the flip-flops. When both

Data Disable inputs are low, data at the D inputs are loaded into

their respective flip-flops on the next positive transition of the

clock input. Output Disable inputs are also provided. When the

Output Disable inputs are both low, the normal logic states of the

four outputs are available to the load. The outputs are disabled

independently of the clock by a high logic level at either Output

Disable input, and present a high impedance.

FEATURES

* Three-state outputs

* Input disabled without gating the clock

* Maximum input current of 1μA at 18V

temperature range;100nA at 18V and 25°C

1V at VDD=5V

2V at VDD=10V

2.5V at VDD=15V

* 5V,10V,and 15V parametric ratings
