74LVXC4245MTCX

The 74LVXC4245MTCX is a 8-bit dual-supply configurable voltage Interface Transceiver with 3-state outputs. It is suitable for PCMCIA and other real time configurable I/O applications. The VCCA pin accepts a 5V supply level. The A port is a dedicated 5V port. The VCCB pin accepts a 3 to 5V supply level. The B port is configured to track the VCCB supply level respectively. A 5V level on the VCC pin will configure the I/O pins at a 5V level and a 3V VCC will configure the I/O pins at a 3V level. 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.

• Control inputs compatible with TTL level
• Outputs source/sink up to 24mA
• Guaranteed simultaneous switching noise level and dynamic threshold performance
• Implements proprietary EMI reduction circuitry
• Flexible VCCB operating range
• Allows B port and VCCB to float simultaneously when OE# is HIGH
• Functionally compatible with the 74 series 245
