DESCRIPTION/ORDERING INFORMATION

This single-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is

designed to track V_CCA. V_CCAaccepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track

V_CCB. V_CCBaccepts any supply voltage from 1.2 V to 3.6 V. This allows for universal low-voltage bidirectional

translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.

The SN74AVCH1T45 is designed for asynchronous communication between data buses. The device transmits

data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the

direction-control (DIR) input.

The SN74AVCH1T45 is designed so that the DIR input is powered by V_CCA

(2) DBV/DCK: The actual top-side marking has one additional character that designates the assembly/test site.

YZP: The actual top-side marking has three preceding characters to denote year, month, and sequence code, and one following

character to designate the assembly/test site. Pin 1 identifier indicates solder-bump composition (1 = SnPb, • = Pb-free).
