DESCRIPTION/ORDERING INFORMATION (CONTINUED)
SN54ALVTH16374 , , SN74ALVTH16374
2.5-V/3.3-V 16-BIT EDGE-TRIGGERED D-TYPE FLIP-FLOPS
WITH 3-STATE OUTPUTS
SCES068G – JUNE 1996 – REVISED NOVEMBER 2006
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.
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.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
When V
CC
is between 0 and 1.2 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 1.2 V, 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 SN54ALVTH16374 is characterized for operation over the full military temperature range of –55 ° C to 125 ° C.
The SN74ALVTH16374 is characterized for operation from –40 ° C to 85 ° C.
