PI74ALVCHT16501

18-Bit Universal Bus Transceiver

With 3-State Outputs

ProductFeatures

PI74ALVCHT16501isdesignedforlowvoltageoperation

ProductDescription

Pericom Semiconductors PI74ALVCH series of logic circuits are

produced using the Companys advanced 0.5 micron CMOS

technology, achieving industry leading speed.

VCC =2.3Vto3.6V

Hysteresis on all inputs

Typical VOLP (Output Ground Bounce) < 0.8V

atVCC =3.3V,TA =25°C

The18-bitPI74ALVCHT16501univeralbustransceiverisdesigned

for2.3Vto3.6VVccoperation.

Typical VOHV (Output VOH Undershoot) < 2.0V

atVCC =3.3V,TA =25°C

Data flow in each direction is controlled by Output Enable (OEAB

andOEBA),LatchedEnable(LEAB.ForA-to-Bdataflow,thedevice

operatesinthetransparentmodewhenLEABisHIGH.WhenLEAB

isLOW,theAdataislatchedifCLKABisheldatahighorlowlogic

level. If LEAB is LOW, the A-bus is stored in the latch/flip-flop on

the high-to-low transition of CLKAB. When OEAB is HIGH, the

outputsareactive.WhenOEABisLOW,theoutputsareinthehigh-

impedance state.

5V Tolerant inputs andoutputs

Bus Hold retains last active bus state during 3-state

eliminates the need for external pullup resistors

Industrial operation at 40°C to +85°C

Toensurethehigh-impedancestateduringpoweruporpowerdown,

OEBA should be tied to Vcc through a pull-up resistor and OEAB

should be tied to GND through a pulldown resistor; the minimum

value of the resistor is determined by the current-sinking capability

of the driver.
