description
The
edge-triggered D-type flip-flops with 3-state
outputs designed specifically for driving highly
capacitive or relatively low-impedance loads.
They are particularly suitable for implementing
buffer registers, I/O ports, bidirectional bus
drivers, and working registers.
’AHC16374
devices
are
16-bit
These devices 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 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 the 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.
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.
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.
The SN54AHC16374 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74AHC16374 is characterized for operation from –40
°
C to 85
°
C.
