SN74ALVC164245DL

The SN74ALVC164245DL is designed as 16-bit (dual-octal) noninverting bus transceiver contains two separate supply rails for asynchronous communication between data buses. To ensure the high-impedance state of SN74ALVC164245DL during power up or power down, the output-enable (OE) input 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.

SN74ALVC164245DL has two features. (1)Member of the texas instruments widebus family. (2)Latch-up performance exceeds 250mA per JESD 17. Those are all the main features.

Some absolute maximum ratings of SN74ALVC164245DL have been concluded into several points as follow. (1)Its supply voltage range would be from -0.5V to 4.6V for Vcca and would be from -0.5V to 6V for Vccb. (2)Its input voltage range would be from -0.5V to 6V except IO ports and would be from -0.5V to Vcca+0.5V for IO port A and would be from -0.5V to Vccb+0.5V for IO port B. (3)Its input clamp current would be -50mA. (4)Its output clamp current would be -50mA. (5)Its continuous output current would be +/-50mA. (6)Its continuous current through each Vcc or GND would be +/-100mA. (7)Its package thermal impedance would be 63°C/W. (8)Its storage temperature range would be from 65°C to 150°C. SN74ALVC164245DL should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of SN74ALVC164245DL at Vcca=2.7V to 3.6V and Vccb=4.5V to 5.5V are concluded as follow. (1)Its output high voltage (B to A) would be min Vcc-0.2V at Ioh=-100uA and would be min 2.2V at Ioh=-12mA and would be min 2V at Ioh=-24mA. (2)Its output voltage high A to B would be min 4.3V at Ioh=-100uA and Vccb=4.5V and would be min 5.3V at Vccb=5.5V and Ioh=-100uA. And so on.
