74AXP1T45 1-bit dual supply translating transceiver; 3-state Rev. 1 — 25 June 2020 Product data sheet 1. General description The 74AXP1T45 is a single bit, dual supply transceiver with 3-state output that enables bidirectional level translation. It features 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 0.9 V and 5.5 V making the device suitable for translating between any of the low voltage nodes (0.9 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V). No power supply sequencing is required and output glitches during power supply transitions are prevented using patented circuitry. As a result glitches will not appear on the outputs for supply transitions during power-up/down between 20 mV/μs and 5.5 V/s. Pins A and DIR 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 device is 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 and B are in the high-impedance OFF-state. 2.

Bidirectional logic level-shifting application Fig. 16 shows the 74AXP1T45 being used in a bidirectional logic level-shifting application. Since the device does not have an output enable pin, the system designer should take precautions to avoid bus contention between system-1 and system-2 when changing directions.

Bidirectional logic level-shifting application Table 18 gives a sequence that will illustrate data transmission from system-1 to system-2 and then from system-2 to system-1. Table 18. Description bidirectional logic level-shifting application H = HIGH voltage level; L = LOW voltage level; Z = high-impedance OFF-state. State DIR CTRL I/O-1 I/O-2 Description 1 H output input system-1 data to system-2 2 H Z Z system-2 is getting ready to send data to system-1. I/O-1 and I/O-2 are disabled. The bus-line state depends on bus hold. 3 L Z Z DIR bit is set LOW. I/O-1 and I/O-2 still are disabled. The bus-line state depends on bus hold. 4 L input output system-2 data to system-1 12.3. Enable times Calculate the enable times for the 74AXP1T45 using the following formulas: • • Direction A to B: • tPZL (DIR to B) = tPHL (A to B) + tPHZ (DIR to A) • tPZH (DIR to B) = tPLH (A to B) + tPLZ (DIR to A) Direction B to A: • tPZL (DIR to A) = tPHL (B to A) + tPHZ (DIR to B) • tPZH (DIR to A) = tPLH (B to A) + tPLZ (DIR 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 74AXP1T45 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. 74AXP1T45 Product data sheet All information provided in this document is subject to legal disclaimers.
