Nexperia USA Inc. 74LVC162245ADL,112

Overview

74LVC162245ADL,112 from Nexperia is a 16-bit dual 8-bit bidirectional transceiver with integrated 30 Ω series termination resistors, 3-state outputs, and 5 V tolerant I/O. It operates from 1.2 V to 3.6 V supply, supports mixed-voltage translation between 3.3 V and 5 V systems, and features independent direction (1DIR/2DIR) and output enable (1OE/2OE) controls per 8-bit port. Used in high-speed bus interface applications including memory expansion and FPGA-to-ASIC data routing.

For engineers reviewing the 74LVC162245ADL,112 datasheet, 74LVC162245ADL,112 pinout, 74LVC162245ADL,112 application, or 74LVC162245ADL,112 equivalent, this device delivers deterministic bidirectional data flow with IOFF partial power-down protection, Schmitt-trigger inputs for noise immunity, and bus hold on data inputs (in LVCH variant), making it suitable for industrial control backplanes and embedded system interconnects requiring robust level-shifting and signal integrity.

Technical Context

This transceiver implements two independent 8-bit bidirectional data paths, each with dedicated direction and output-enable inputs-enabling flexible configuration as either one 16-bit or two concurrent 8-bit transceivers. Its IOFF circuitry actively disables outputs during power-down to prevent backflow current, satisfying JEDEC JESD78 requirements for partial power-down operation.

All inputs feature Schmitt-trigger action for reliable operation with slow-rising signals, and the 74LVCH162245A variant includes bus hold on data inputs (not present in LVC-only version). The device integrates 30 Ω series termination resistors on all I/O pins to reduce transmission line reflections in high-speed parallel buses operating up to 200 MHz.

FAQ

Does 74LVC162245ADL,112 support true bidirectional operation on each pin?

Yes-each of the 16 I/O pins functions bidirectionally under control of its associated DIR and OE inputs. When 1OE is LOW and 1DIR is HIGH, data flows from port A (1A0–1A7) to port B (1B0–1B7); reversing DIR reverses the direction. Independent control per 8-bit bank allows asymmetric read/write operations.

Can 74LVC162245ADL,112 be used with a 1.2 V supply and 3.3 V inputs?

Yes-the device accepts input voltages up to 5.5 V regardless of V_CC, so 3.3 V signals are safely tolerated at V_CC = 1.2 V. Output HIGH voltage will be ~1.0 V (min) under 2 mA load, sufficient to drive compatible 1.2 V logic inputs with margin.

What is the thermal performance difference between TSSOP48 and TVSOP48 packages?

The TSSOP48 (SOT362-1) has higher thermal resistance: P_tot derates linearly at 12.2 mW/K above 109 °C, while the TVSOP48 (SOT480-1) derates at 5.5 mW/K above 60 °C. At full 500 mW dissipation, TSSOP48 supports higher ambient temperatures in forced-air cooling, whereas TVSOP48 requires tighter thermal management due to smaller body size.

Is bus hold functionality present on 74LVC162245ADL,112?

No-bus hold is exclusive to the 74LVCH162245A variant. The 74LVC162245A (including 74LVC162245ADL,112) lacks internal bus hold circuitry on data inputs. Unused inputs must be externally terminated to V_CC or GND to prevent floating states and increased ICC.
