Nexperia USA Inc. 74LVT162245BDL,118

Overview

74LVT162245BDL,118 from Nexperia is a 3.3 V 16-bit bidirectional transceiver with integrated 30 Ω series output termination resistors, dual independent direction controls (1DIR/2DIR), dual 3-state enables (1OE/2OE), and bus-hold inputs for unused pins. It operates across 2.7–3.6 V supply, delivers ±12 mA drive strength, and supports high-speed data transfer in backplane and memory interface applications.

For engineers reviewing the 74LVT162245BDL,118 datasheet, 74LVT162245BDL,118 pinout, 74LVT162245BDL,118 application, or 74LVT162245BDL,118 equivalent, this device is selected for robust 3.3 V bus interfacing where internal termination, overvoltage-tolerant inputs (to 5.5 V), and live insertion capability are required in industrial control and telecom backplane designs.

Technical Context

The 74LVT162245BDL,118 implements two independent 8-bit transceiver sections-each with dedicated DIR and OE inputs-enabling flexible 8-bit or unified 16-bit data flow. Its BiCMOS architecture combines bipolar speed with CMOS low power, achieving typical propagation delays of 2.5 ns (tPLH) and 2.2 ns (tPHL) at 3.3 V.

Each output integrates a 30 Ω series resistor to match transmission line impedance, eliminating external termination components. Bus-hold circuitry maintains stable logic states on un-driven inputs without pull-ups, while IOFF protection ensures minimal leakage during partial power-down.

FAQ

What is the maximum data rate supported by the 74LVT162245BDL,118?

The device achieves typical propagation delays of 2.2–2.5 ns at 3.3 V, supporting clean signal edges up to 200+ MHz in well-terminated point-to-point links. Real-world throughput depends on trace length, load capacitance, and termination quality-but the 30 Ω series resistance and low skew make it suitable for DDR-200-class memory interfaces and backplane buses.

Can the 74LVT162245BDL,118 interface directly with 5 V logic?

Yes-the inputs tolerate up to 5.5 V regardless of VCC level, allowing safe connection to 5 V peripherals without level shifters. However, outputs swing only to VCC (max 3.6 V), so driving 5 V TTL inputs requires verifying VIH thresholds; for guaranteed compatibility, use with 3.3 V–tolerant 5 V receivers (e.g., 74LVT or 74ALVT families) is recommended.

How does the bus-hold feature affect power consumption?

Bus-hold draws ±75–130 μA per inactive input at 3 V, increasing total ICC by <100 μA in typical idle conditions. This is negligible compared to dynamic switching current and avoids the higher static draw (and board area) of external 10–100 kΩ pull-up/down resistors-making it net power-positive in systems with many unused I/Os.

Is the 74LVT162245BDL,118 pin-compatible with other 74-series transceivers?

It shares the TSSOP48 footprint and functional pinout with industry-standard 16-bit transceivers like the 74LVC16245A and 74ALVCH162245, but differs in electrical behavior: built-in termination, bus-hold, and IOFF are unique to this variant. Mechanical replacement is possible, but electrical validation-including timing, loading, and power-up state-is required before substitution.
