Nexperia USA Inc. 74LVC16245ADGVJ

Overview

74LVC16245ADGV from Nexperia is a 16-bit 3-state bus transceiver with dual direction control (1DIR/2DIR) and dual output enables (1OE/2OE), operating from 1.2 V to 3.6 V supply, tolerant to 5.5 V inputs, and rated for -40 °C to +125 °C. It supports bidirectional data flow across two independent 8-bit ports or as a unified 16-bit interface in mixed-voltage systems.

For engineers reviewing the 74LVC16245ADGV datasheet, 74LVC16245ADGV pinout, 74LVC16245ADGV application, or 74LVC16245ADGV equivalent, this device is selected for high-density PCBs requiring low-noise 3-state bus isolation, voltage-level translation between 3.3 V and 5 V domains, and partial power-down capability via IOFF.

Technical Context

This transceiver implements CMOS logic with Schmitt-trigger inputs for noise immunity and robust timing with input rise/fall rate support up to 20 ns/V at 1.2 V and 10 ns/V at 3.3 V. Its dual OE/DIR architecture enables independent control of two 8-bit data paths, allowing asymmetric enable/disable sequencing and flexible bus arbitration.

The IOFF circuit actively disables outputs during power-down to block backflow current, while bus hold (on 74LVCH variant only) eliminates external pull-ups on unused data inputs. The device complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 across its full voltage range.

FAQ

Can 74LVC16245ADGV operate at 1.2 V while driving 5 V-tolerant loads?

Yes. The device operates from 1.2 V to 3.6 V supply and accepts input voltages up to 5.5 V regardless of VCC level. At 1.2 V supply, output HIGH voltage is guaranteed ≥1.08 V (VIH min), sufficient to drive compatible 1.2 V or 1.8 V receivers-but not directly assert 5 V logic HIGH. External pull-ups or level-shifting remain required for true 5 V output assertion.

What is the function of the two DIR pins, and can they be tied together?

1DIR and 2DIR independently control data direction for Port A/B and Port C/D (first and second 8-bit groups). They may be tied together if both ports require identical directionality-but doing so forfeits independent lane control. Separating them enables asymmetric configurations, such as A→B while C←D, useful in multiplexed bus arbitration schemes.

How does the IOFF feature behave during power sequencing?

When VCC drops below ~0.8 V, the IOFF circuit automatically disables all outputs into high-impedance state-even if OE remains LOW-preventing reverse current flow from live I/O lines into the unpowered VCC rail. This behavior is specified down to VCC = 0 V and tested per JEDEC JESD78.

Is bus hold functionality present on 74LVC16245ADGV?

No. Bus hold is exclusive to the 74LVCH16245A variant (e.g., 74LVCH16245ADGV). The 74LVC16245ADGV lacks internal bus hold circuitry on data inputs; external pull-up/pull-down resistors must be used on unused inputs to prevent floating states and EMI susceptibility.
