Description

The 74AVCH1T45 is a single bit, dual supply transceiver with 3-state outputs suitable for transmitting a single logic bit across different voltage domains. The 74AVCH1T45 is a variant of the 74AVC1T45 that includes a bus hold feature at each input. The A input/output pin is designed to track VCCA while the B input/output tracks VCCB. This arrangement allows for universal low-voltage translation between any voltages from 1.2V to 3.6V. The Direction pin (DIR) controls the direction of the transceiver and in a logic voltage related to VCCA. When a high logic level is applied to DIR the A pin becomes an input and the B pin becomes the output. Conversely the roles of A and B are reversed when DIR is asserted low.
