General Description

The SN74LVCH8T245 is an 8-bit noninverting bus transceiver that uses two separate configurable power-supply rails.

The A port is designed to track VCCA, which accepts any supply voltage from 1.65 V to 5.5 V.

The B port is designed to track VCCB, which also accepts any supply voltage from 1.65 V to 5.5 V.

Key Features

  • Control inputs (DIR and OE) VIH and VIL levels are referenced to VCCA.
  • Bus hold on data inputs eliminates the need for external pullup and pulldown resistors.
  • VCC isolation.
  • Fully configurable dual-rail design.
  • Ioff supports Partial-Power-Down node operation.
  • Latch-up performance exceeds 100 mA per JESD 78, class II.
  • ESD protection exceeds JESD 22 2.
