description
The
′
ABT377 are 8-bit positive-edge-triggered
D-type flip-flops with a clock (CLK) input. They are
particularly suitable for implementing buffer and
storage registers, shift registers, and pattern
generators.
Data (D) input information that meets the setup
time requirements is transferred to the Q outputs
on the positive-going edge of the clock pulse if the
common clock-enable (CLKEN) input 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 the buffered clock
(CLK) input is at either the high or low level, the
D input signal has no effect at the output. The
circuits are designed to prevent false clocking by
transitions at CLKEN.
The SN74ABT377 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count
and functionality of standard small-outline packages in less than half the printed-circuit-board area.
The SN54ABT377 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C. The
SN74ABT377 is characterized for operation from –40
°
C to 85
°
C.
