74LVC1T45
SINGLE BIT DUAL POWER SUPPLY TRANSLATING TRANSCEIVER WITH 3 STATE OUTPUTS
Description
The 74LVC1T45 is a single-bit, dual-supply transceiver with tri-state outputs suitable for transmitting a single logic bit across different voltage domains. 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 1.65V to 5.5V. 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.
