Nexperia USA Inc. 74LVC16245ADGG,118

Overview

74LVC16245ADGG,118 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 while accepting 5 V-tolerant inputs. It supports bidirectional data flow across two independent 8-bit ports or as a unified 16-bit path, with Schmitt-trigger inputs for noise immunity and IOFF circuitry enabling partial power-down in mixed-voltage systems. Used in FPGA-to-ASIC interconnects, memory expansion buses, and industrial PLC backplanes.

For engineers reviewing the 74LVC16245ADGG,118 datasheet, 74LVC16245ADGG,118 pinout, 74LVC16245ADGG,118 application, or 74LVC16245ADGG,118 equivalent, this device delivers verified 5 V input tolerance, sub-6 ns propagation delay at 3.3 V, dual-port isolation via separate OE/DIR controls, and TSSOP48 packaging compatible with high-density PCB layouts.

Technical Context

This transceiver implements true bidirectional flow-through architecture with independent 8-bit A/B port groups. Each group features dedicated direction (DIR) and output enable (OE) signals, allowing simultaneous or staggered control of data direction and tri-state behavior without internal contention.

Its IOFF circuitry actively disables outputs during power-down, blocking backflow current when VCC = 0 V, while Schmitt-trigger inputs ensure robust operation with slow-rising signals up to 20 ns/V (at 1.2 V). Bus hold functionality is absent in the LVC variant (present only in LVCH), confirming this part requires external termination on unused inputs.

FAQ

Is the 74LVC16245ADGG,118 pin-compatible with the 74LVCH16245ADGG?

Yes-both share identical TSSOP48 (SOT362-1) pinout, supply range, timing, and electrical specifications. The sole functional difference is the absence of bus hold circuitry in the LVC variant, meaning unused inputs require external pull-up/pull-down resistors to prevent floating states.

What is the maximum data rate supported by this transceiver?

While not specified as a serial data rate, the device supports parallel bus frequencies up to 100 MHz based on its 4.5 ns max propagation delay (VCC = 3.0–3.6 V) and 5.5 ns max disable time. System-level timing must account for PCB trace delays and load capacitance, but the IC itself meets AC specifications for 100 MHz synchronous bus operation.

Does this part support hot-plug operation?

Yes-its IOFF circuitry actively disables outputs when VCC = 0 V, preventing back-current flow into powered sections of the system. This enables safe insertion/removal of daughter cards in live backplanes, provided external power sequencing controls VCC ramp rates to stay within absolute maximum ratings.

Can I use 74LVC16245ADGG,118 to interface a 3.3 V microcontroller with a 5 V EEPROM?

Yes-the inputs tolerate up to 5.5 V regardless of VCC, allowing direct connection of 5 V EEPROM outputs to the transceiver's B-side inputs. Configure DIR to route data from EEPROM (B) to MCU (A), and use OE to tri-state during MCU writes. No level shifters needed for input paths.
