Pericom Semiconductor's PI74ALVCH series of logic circuits are produced in the Company's advanced 0.5 micron CMOS technology, achieving industry leading speed.
The PI74ALVCH162820 is a 10-bit flip-flop designed for 2.3V to 3.3V VCC operation. The PI74ALVCH162820 is designed with edgetriggered D-type flip-flops. On the positive transition of clock (CLK) input, the device provides true data at the Q outputs.
A buffered output-enable (OE) input can be used to place the ten outputs in either a normal logic state (HIGH or LOW level) or a highimpedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capacity to drive bus lines without the need for interface or pullup components. OE does not affect the internal operation of the flip-flops. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.
The outputs, which are designed to sink up to 12mA, include 26W resistors to reduce overshoot and undershoot.
The PI74ALVCH162820 has "Bus Hold" which retains the data input's last state whenever the data input goes to high-impedance preventing "floating" inputs and eliminating the need for pullup/ down resistors.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
