SN74AVC4T234 - 4-Bit Dual-Supply Unidirectional Noninverting Voltage Translator

Description

This 4-bit non-inverting bus transceiver uses two separate configurable power-supply rails to enable asynchronous communication between B-port inputs and A-port outputs.

The A port is designed to track VCCA while the B port is designed to track VCCB.

Features

  • Wide operating VCC range of 0.9 V to 3.6 V.
  • 3.6-V I/O Tolerant to support mixed-mode signal operation.
  • Max tpd of 3.7 ns at 3.3 V.
  • Balanced propagation delays: tPLH = tPHL.
  • Low static-power consumption, 5-μA Max ICC.
  • Outputs disabled if either VCC goes to 0V.
  • ±3-mA Output drive at 1.8 V.
  • 26-Ω series resistor on A-side outputs.
  • Ioff supports partial power-down-mode operation.
  • Input hysteresis allows slow in.
