Product details
Overview
74LVT16245BEV,118 from Nexperia is a 3.3 V, 16-bit non-inverting bidirectional transceiver with 3-state bus-compatible outputs in both directions, ±64 mA/−32 mA drive capability, TTL-level I/O compatibility with 5 V systems, and bus hold inputs eliminating external pull-ups. It serves as a level-shifting data interface in high-speed backplane and memory subsystem interconnects.
For engineers reviewing the 74LVT16245BEV,118 datasheet, 74LVT16245BEV,118 pinout, 74LVT16245BEV,118 application, or 74LVT16245BEV,118 equivalent, this page delivers verified package mapping (VFBGA56), functional pin roles, bus hold behavior, propagation delays down to 1.0 ns, and real-world substitution guidance for logic-level translation in industrial control and telecom infrastructure designs.
Technical Context
The 74LVT16245BEV,118 implements dual 8-bit bidirectional data paths controlled by independent direction (nDIR) and output enable (nOE) inputs per port, enabling flexible data flow arbitration without external logic. Its BiCMOS architecture supports TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) while operating from a 2.7–3.6 V supply.
It features live insertion/extraction support, power-up 3-state behavior, and robust ESD protection (HBM > 2000 V, MM > 200 V). Bus hold circuitry maintains valid logic states on unused inputs at ±75–135 µA, preventing floating-node oscillation in unterminated buses.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional bus interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVTH16245BEV,118 | Higher drive (+64 mA / −64 mA vs. +64 mA / −32 mA); identical pinout and VFBGA56 package. | Required where symmetrical sink/source capability is needed for driving terminated transmission lines. | Select when driving 50 Ω stubs or long traces requiring matched push-pull strength on both logic states. |
| SN74LVC16245APAG | TSSOP48 package (not VFBGA); 3.3 V only (non-5 V tolerant); lower drive (±24 mA). | Suitable for cost-sensitive, space-tolerant industrial controls where 5 V compatibility is unnecessary. | Choose for legacy TSSOP-based designs or where thermal dissipation favors larger package over VFBGA. |
Compared with 74LVTH16245BEV,118 and SN74LVC16245APAG, the 74LVT16245BEV,118 uniquely balances 5 V tolerance, asymmetric high-current sourcing, and ultra-compact VFBGA56 packaging-making it optimal for space-constrained, mixed-voltage embedded interfaces requiring robust bus hold and live-insertion support.

FAQ
What is the maximum clock frequency supported by the 74LVT16245BEV,118 in a parallel bus application?
The 74LVT16245BEV,118 does not operate on a clock signal-it is an asynchronous transceiver. Its usable data rate is determined by propagation delay (1.0–3.3 ns) and system setup/hold timing. In practice, it reliably supports parallel bus frequencies up to 100 MHz when paired with appropriate trace length and termination, as confirmed by Nexperia's test data at 10 MHz with 50 pF load.
Does the 74LVT16245BEV,118 require external pull-up resistors on its data pins?
No, the 74LVT16245BEV,118 integrates bus hold circuitry on all data I/O pins (1A0–1A7, 1B0–1B7, 2A0–2A7, 2B0–2B7), providing ±75–135 µA holding current. This eliminates the need for external pull-up or pull-down resistors on unused or undriven lines, reducing BOM cost and PCB area.
Can the 74LVT16245BEV,118 safely interface with 5 V microcontrollers while powered at 3.3 V?
Yes-the 74LVT16245BEV,118 features 5 V tolerant inputs, allowing it to accept VI up to 5.5 V while operating from a 3.3 V supply. Its TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) ensure reliable recognition of 5 V logic levels without damage or level-shifting circuitry.
What is the thermal performance of the 74LVT16245BEV,118 in the VFBGA56 package?
The 74LVT16245BEV,118 in VFBGA56 has a total power dissipation rating of 1000 mW at −40 °C to +85 °C ambient. Above +70 °C, Ptot derates linearly at 1.8 mW/K. Its eight GND balls and four VCC balls provide low-thermal-resistance paths, enabling stable operation in compact, sealed enclosures typical of industrial edge devices.
Is the 74LVT16245BEV,118 pin-compatible with other packages in the same family?
No-the 74LVT16245BEV,118 uses the VFBGA56 (SOT702-1) package with 56 balls and a 0.5 mm pitch, differing electrically and mechanically from SSOP48 (SOT370-1), TSSOP48 (SOT362-1), and HXQFN60 (SOT1134-2) variants. Pin functions are consistent across the family, but physical layout, ball count, and routing requirements are unique to SOT702-1.
