description
The ’ABT16374 is a 16-bit edge-triggered D-type
flip-flop with 3-state outputs designed specifically
for driving highly capacitive or relatively
low-impedance loads. It is particularly suitable for
implementing
buffer
bidirectional bus drivers, and working registers.
registers,
I/O
ports,
The device can be used as two 8-bit flip-flops or one 16-bit flip-flop. On the positive transition of the clock (CLK)
input, the Q outputs of the flip-flop take on the logic levels set up at the data (D) inputs.
A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high
or low logic levels) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive
the bus lines significantly. The high-impedance state and the increased drive provide the capability to drive bus
lines without need for interface or pullup components
The output enable (OE) does not affect internal operations of the flip-flop. Old data can be retained or new data
can be entered while the outputs are in the high-impedance state.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN74ABT16374 is packaged in TI’s shrink small-outline package (DL), which provides twice the I/O pin
count and functionality of standard small-outline packages in the same printed-circuit-board area.
The SN54ABT16374 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74ABT16374 is characterized for operation from –40

C to 85
