Overview

The LVXC3245 is a 24-pin dual-supply, 8-bit configurable voltage interface transceiver suited for PCMCIA and other real time configurable I/O applications. The VCCA pin accepts a 3V supply level. The A Port is a dedicated 3V port. The VCCB pin accepts a 3V-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. The A Port should interface with a 3V 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.

  • This product is general usage and suitable for many different applications.

  • Bidirectional interface between 3V and 3V-to-5V buses
  • Control inputs compatible with TTL level
  • Outputs source/sink up to 24 mA
  • 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

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
