description

This 10-bit flip-flop is designed specifically for low-voltage(3.3-V) V_CC operation

The flip-flops of the SN74ALVC162820 are edge-triggered D-typeflip-flops. On the positive transition of the clock (CLK) input, thedevice provides true data at the Q outputs.

A buffered output-enable () input can be used to place the eight outputs in eithera normal logic state (high or low logic levels) or a high-impedancestate. In the high-impedance state, the outputs neither load nordrive the bus lines significantly. The high-impedance state andincreased drive provide the capability to drive bus lines withoutneed for interface or pullup components.

The output-enable ()input does not affect the internal operations of the flip-flops. Olddata can be retained or new data can be entered while the outputs arein the high-impedance state.

The outputs, which are designed to sink up to 12 mA, include 26-resistors to reduce overshoot andundershoot.

Active bus-hold circuitry is provided to hold unused or floatingdata inputs at a valid logic level.

The SN74ALVC162820 is available in TI's shrink small-outline (DL)and thin shrink small-outline (DGG) packages, which provide twice theI/O pin count and functionality of standard small-outline packages inthe same printed-circuit-board area.

The SN74ALVC162820 is characterized for operation from -40°Cto 85°C.
