2 / 21 page www.ti.com 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 VCC 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 VCC 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.
