74AXP1T57GXX

Overview

The Nexperia 74AXP1T57GXX is a dual supply configurable multiple function gate featuring Schmitt-trigger inputs. It provides one circuit with three data inputs (A, B, C) and one output (Y). The device supports independent input supply voltage (VCCI) ranging from 0.7 V to 2.75 V and output supply voltage (VCCO) ranging from 1.2 V to 5.5 V. This architecture enables voltage level translation between different logic domains. The component is housed in an X2SON8 package (SOT1233-2) with dimensions of 1.35 x 0.8 x 0.32 mm.

Feature Summary

• Configurable logic functions including AND, OR, NAND, NOR, XNOR, inverter, and buffer via three-bit input configuration.
• Dual supply architecture allows independent voltage levels for input and output domains to facilitate level translation.
• IOFF circuitry prevents damaging backflow current during partial power-down applications.
• Schmitt-trigger inputs provide high noise immunity and tolerance for slow input rise and fall times.

Applications

• Voltage level translation between mixed 3.3 V and 5 V environments.
• Partial power-down mode operation in systems requiring low static power consumption.
• Logic function reconfiguration in space-constrained designs using the X2SON8 package.

Procurement Notes

Verify the specific ordering suffix 'GX' corresponds to the SOT1233-2 (X2SON8) thermal-enhanced package variant. Confirm that the required operating temperature range aligns with the -40 °C to +125 °C specification. Ensure design compatibility with the dual supply requirements for VCCI and VCCO before procurement.

Selection Notes

Select this component when a single gate requires configurable logic functionality alongside voltage translation capabilities. The X2SON8 package offers a compact footprint suitable for dense PCB layouts. Consider the IOFF feature if the application involves partial power-down states to protect downstream components from backflow currents.

Part Context

This device belongs to the 74AXP family of Si-gate CMOS devices designed for low power and high performance. The 74AXP1T57 specifically addresses needs for flexible logic implementation in dual-supply systems. It complements other Nexperia logic products by offering configurable gates rather than fixed-function inverters or buffers.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical specifications against any alternative configurable gates before substitution.
