1 / 9 page © Semiconductor Components Industries, LLC, 2014 September, 2014 − Rev. 7 1 Publication Order Number: MC74LVXC3245/D MC74LVXC3245 Configurable Dual Supply Octal Transceiver with 3−State Outputs for 3 V Systems The 74LVXC3245 is a 24−pin dual−supply, octal configurable voltage interface transceiver especially well suited for PCMCIA and other real time configurable I/O applications. The VCCA pin accepts a 3.0 V supply level; the A port is a dedicated 3.0 V port. The VCCB pin accepts a 3.0 V−to−5.0 V supply level. The B port is configured to track the VCCB supply level. A 5.0 V level on the VCCB pin will configure the I/O pins at a 5.0 V level and a 3.0 V VCCB will configure the I/O pins at a 3.0 V level. The A port interfaces with a 3.0 V host system and the B port to the card slots. This device will allow the VCCB voltage source pin and I/O pins on the B port to float when OE is High. This feature is necessary to buffer data to and from a PCMCIA socket that permits PCMCIA cards to be inserted and removed during normal operation. The Transmit/Receive (T/R) input determines the direction of data flow. Transmit (active−High) enables data from the A port to B port. Receive (active−Low) enables data from the B port to the A port. Features • Bidirectional Interface Between 3.0 V and 3.0 V/5.0 V Buses • Control Inputs Compatible with TTL Level • Outputs Source/Sink Up to 24 mA • Guaranteed Simultaneous Switching Noise Level and Dynamic Threshold Performance • Available in SOIC and TSSOP Packages • Flexible VCCB Operating Range • Allows B Port and VCCB to Float Simultaneously When OE is High • Functionally Compatible With the 74 Series 245 • These Devices are Pb−Free and are RoHS Compliant http://onsemi.com MARKING DIAGRAMS SOIC−24 DW SUFFIX CASE 751E See detailed ordering and shipping information in the package dimensions section on page 5 of this data sheet.
