74LVC1T45; 74LVCH1T45 Dual supply translating transceiver; 3-state Rev. 9 — 10 February 2022 Product data sheet 1. General description The 74LVC1T45; 74LVCH1T45 are single bit, dual supply transceivers with 3-state outputs that enable bidirectional level translation. They feature two 1-bit input-output ports (A and B), a direction control input (DIR) and dual supply pins (VCC(A) and VCC(B)). Both VCC(A) and VCC(B) can be supplied at any voltage between 1.2 V and 5.5 V making the device suitable for translating are referenced to VCC(A) and pin B is referenced to VCC(B). A HIGH on DIR allows transmission from A to B and a LOW on DIR allows transmission from B to A. The devices are fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing any damaging backflow current through the device when it is powered down. In suspend mode when either VCC(A) or VCC(B) are at GND level, both A port and B port are in the high-impedance OFF-state. Active bus hold circuitry in the 74LVCH1T45 holds unused or floating data inputs at a valid logic level. 2. Features and benefits

tPZH (DIR to A) = tPLZ (DIR to B) + tPLH (B to A)
tPZL (DIR to A) = tPHZ (DIR to B) + tPHL (B to A)
tPZH (DIR to B) = tPLZ (DIR to A) + tPLH (A to B)
tPZL (DIR to B) = tPHZ (DIR to A) + tPHL (A to B) In a bidirectional application, these enable times provide the maximum delay from the time the DIR bit is switched until an output is expected. For example, if the 74LVC1T45; 74LVCH1T45 initially is transmitting from A to B, then the DIR bit is switched, the B port of the device must be disabled before presenting it with an input. After the B port has been disabled, an input signal applied to it appears on the corresponding A port after the specified propagation delay. 74LVC_LVCH1T45 All information provided in this document is subject to legal disclaimers. © Nexperia B.V. 2022.
