OCTAL D-TYPE FLIP-FLOPS
WITH CLOCK ENABLE
DESCRIPTION
The device is positive-edge-triggered octal D-type flip-flops
with an enable input.
Information at the data (D) inputs meeting the setup time
requirements is transferred to the Q outputs on the positive-going
edge of the clock (CLK) pulse, if EN is low. Clock triggering
occurs at a particular voltage level and is not directly related to
the transition time of the positive-going pulse. When CLK is at
either the high or low level, the D input has no effect at the output.
These devices are designed to prevent false clocking by
transitions at EN .
FEATURES
* Wide Operating Voltage Range of 2V to 6V
* Outputs Can Drive Up To 10 LSTTL Loads
* Low Power Consumption, ICC=8μA (Max.)
* Typical tPD=12ns
* ±4mA Output Drive at 5V
* Low Input Current of 1μA Max.
* Eight Flip-Flops With Single-Rail Outputs
* Clock Enable Latched to Avoid False Clocking
* Applications Include
- Buffer/Storage Registers
- Shift Registers
- Pattern Generators
