DUAL BIT DUAL POWER SUPPLY TRANSLATING TRANSCEIVER WITH 3 STATE OUTPUTS Description Pin Assignments The 74LVCH2T45 is a dual-bit, dual-supply transceiver with tri-state outputs suitable for transmitting two logic bits across different voltage domains. The direction pin (DIR) and Port A, consisting of pins 1A and 2A, have logic levels in relation to VCC(A) while port B, consisting of pins 1B and 2B have logic levels related to VCC(B). This arrangement allows for universal low-voltage translation between any voltages from 1.2V to 5.5V. When a HIGH logic level is applied to the direction pin, port A pins bee inputs and port B pins are outputs. Conversely, the roles of the...
