Product details
Overview
74LVTN16245BDGG,12 from Nexperia is a 3.3 V, 16-bit non-inverting bus transceiver with dual 3-state outputs, direction control (nDIR), and independent output enable (nOE) per port. It supports bidirectional data flow between 3.3 V and 5 V systems, delivers ±64 mA drive strength, and operates across -40 °C to +85 °C. Used in high-speed backplane and memory interface buffering.
For engineers reviewing the 74LVTN16245BDGG,12 datasheet, 74LVTN16245BDGG,12 pinout, 74LVTN16245BDGG,12 application, or 74LVTN16245BDGG,12 equivalent, key selection criteria include 3.3 V BiCMOS logic compatibility, TTL-level input thresholds, 5 V-tolerant I/O, propagation delay ≤3.3 ns, and TSSOP48 thermal/power behavior under 64 mA sink conditions.
Technical Context
This device implements two independent 8-bit transceiver sections (Port A ↔ Port B), each with dedicated nDIR and nOE controls. Direction is determined by nDIR: LOW enables A→B transfer, HIGH enables B→A transfer. Output state is controlled by active-low nOE - when HIGH, outputs enter high-impedance mode regardless of direction or data.
It uses BiCMOS process technology to achieve TTL-compatible input switching levels (VIL ≤ 0.8 V, VIH ≥ 2.0 V) while operating at 3.3 V supply, and features 5 V-tolerant inputs/outputs without external level shifters. Power-up 3-state and live-insertion support simplify hot-swap system design.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16245ADGGR | Lower drive (±24 mA), 1.65–3.6 V VCC range, no 5 V-tolerant inputs | Requires external level shifting for 5 V interfaces; suited for pure 3.3 V or mixed 1.8/3.3 V systems | Select when cost and power efficiency outweigh 5 V interoperability needs |
| 74ALVC16245PW,118 | Same 5 V-tolerant I/O, but only ±24 mA drive and higher propagation delay (≤5.2 ns) | Acceptable for lower-speed industrial buses where timing margin is relaxed | Choose when thermal budget limits require lower ICC and reduced IOL capability |
Compared with SN74LVC16245ADGGR and 74ALVC16245PW,118, the 74LVTN16245BDGG,12 uniquely combines 5 V-tolerant I/O, ±64 mA sink/source, and sub-3.5 ns propagation in a single 3.3 V BiCMOS device - making it optimal for high-drive, mixed-voltage backplane and memory interface designs where timing and interoperability are critical.

FAQ
What is the maximum allowable VCC voltage for continuous operation?
The absolute maximum VCC is +4.6 V per IEC 60134 limiting values, but recommended operation is strictly 2.7 V to 3.6 V. Exceeding 3.6 V risks parametric shift and accelerated aging, even if within absolute max ratings. Operation above 3.6 V voids guaranteed performance per Table 5.
Can 74LVTN16245BDGG,12 safely interface with a 5 V microcontroller's GPIO without external components?
Yes - all inputs and outputs are 5 V tolerant up to 5.5 V, and VIH/VIL thresholds (≥2.0 V / ≤0.8 V) align with TTL logic levels. No series resistors or level shifters are required when connecting to 5 V microcontrollers operating within their valid output swing.
How does the power-up 3-state feature behave during VCC ramp?
During power-up, outputs remain in high-impedance state until VCC reaches ~1.2 V and stabilizes. This prevents bus contention before supply regulation completes. The feature is intrinsic to the BiCMOS design and requires no external reset sequencing or pull-up/pull-down networks.
Is thermal derating required for sustained 64 mA output current at +85 °C?
No - the 64 mA IOL rating is specified across the full -40 °C to +85 °C range per Table 5. However, total power dissipation must stay within 500 mW (Table 7). At +85 °C ambient, PCB copper area and airflow must ensure junction temperature remains ≤150 °C, as verified by thermal simulation or measurement.
