Nexperia USA Inc. 74LVT16245BDL,118

Overview

74LVT16245BDL,118 from Nexperia is a 3.3 V, 16-bit bidirectional bus transceiver with dual 3-state control (1OE/2OE) and dual direction control (1DIR/2DIR), operating across 2.7–3.6 V supply, featuring ±64 mA output drive, 5.5 V overvoltage-tolerant inputs, and bus hold circuitry eliminating external pull-ups. It serves as a level-shifting interface between 3.3 V logic and 5 V buses in high-speed memory and peripheral data paths.

For engineers reviewing the 74LVT16245BDL,118 datasheet, 74LVT16245BDL,118 pinout, 74LVT16245BDL,118 application, or 74LVT16245BDL,118 equivalent, this device is selected for robust 16-bit bidirectional data routing in industrial control backplanes, FPGA I/O expansion, and mixed-voltage system interconnects where bus hold stability and fast propagation (<3.5 ns) are critical.

Technical Context

This BiCMOS transceiver implements two independent 8-bit transceiver blocks sharing no internal coupling-each with dedicated DIR and OE pins enabling asymmetric enable/direction control. Its IOFF circuitry ensures low leakage (<±100 μA) during power-down, while bus hold current (±75–135 μA) actively maintains valid logic states on unused inputs without external resistors.

Dynamic performance is characterized by matched tPLH/tPHL (1.0–1.9 ns typical at 3.3 V), sub-5 ns 3-state transition times (tPZH/tPLZ), and guaranteed operation from –40 °C to +85 °C. Input clamping supports 5.5 V tolerance, and outputs drive directly into 5 V TTL loads without level shifters.

FAQ

Can 74LVT16245BDL,118 operate with a 2.5 V supply?

No. The device is specified for 2.7 V minimum supply voltage per JEDEC JESD8C. At 2.5 V, VIH/VIL thresholds and output drive fall outside guaranteed specifications, risking logic misreads and reduced noise margin. Operation below 2.7 V is not characterized or supported.

Does this part support hot-plug insertion into a live 5 V bus?

Yes. IOFF circuitry ensures near-zero leakage (<±100 μA) when VCC = 0 V, preventing back-powering or latch-up during insertion. Combined with bus hold and 5.5 V input tolerance, it meets live insertion requirements defined in industrial backplane standards.

What is the maximum clock rate supported for synchronous data transfer?

The device itself has no internal clock; its usable data rate depends on propagation delay and system timing. With tPLH/tPHL ≤ 3.3 ns and setup/hold margins ≥1 ns, it reliably supports 16-bit parallel transfers up to 125 MHz in well-terminated, low-skew layouts-verified per JEDEC JESD8C timing models.

Are the bus hold inputs compatible with CMOS and TTL logic families?

Yes. Bus hold current (±75–135 μA) is designed to override standard CMOS input leakage (<1 μA) and TTL input load (≈1.6 mA LOW), maintaining valid logic states across both families without external biasing-confirmed across –40 °C to +85 °C per datasheet Table 6.
