Overview

The 74VCX16245 is an advanced performance, non-inverting 16-bit transceiver. It is designed for very high-speed, very low-power operation in 1.8V, 2.5V or 3.3V systems.

When operating at 2.5V (or 1.8V) the part is designed to tolerate voltages it may encounter on either inputs or outputs when interfacing to 3.3V busses. It is guaranteed to be over-voltage tolerant to 3.6V.

The VCX16245 is designed with byte control. It can be operated as two separate octals, or with the controls tied together, as a 16-bit wide function. The Transmit/Receive (T/Rbarn) inputs determine the direction of data flow through the bi-directional transceiver. Transmit (active-HIGH) enables data from A ports to B ports; Receive (active-LOW) enables data from B to A ports. The Output Enable inputs (OEn)bar, when HIGH, disable both A and B ports by placing them in a HIGH Z condition.

  • Designed for Low Voltage Operation: VCC = 1.65-3.6V
  • 3.6V Tolerant Inputs and Outputs
  • High Speed Operation: 2.5ns max for 3.0 to 3.6V
    3.0ns max for 2.3 to 2.7V
    6.0ns max for 1.65 to 1.95V
  • Static Drive: +/- 24mA Drive at 3.0V
    +/-18mA Drive at 2.3V
    +/-6mA Drive at 1.65V
  • Supports Live Insertion and Withdrawal
  • IOFF Specification Guarantees High Impedance When VCC = 0V
  • Near Zero Static Supply Current in All Three Logic States (20mA)
    Substantially Reduces System Power Requirements
  • Latchup Performance Exceeds +/-300mA @ 125°C
  • ESD Performance: Human Body Model >2000V; Machine Model >200V

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.)
