Overview
74LVCH16541ADGG:51 from Nexperia is a 16-bit dual 8-bit non-inverting 3-state buffer/line driver with bus hold, operating from 1.2 V to 3.6 V supply, supporting 5 V-tolerant I/O, and rated for −40 °C to +125 °C. It enables bidirectional data isolation in high-density memory and bus interfaces where mixed-voltage signaling occurs.
For engineers reviewing the 74LVCH16541ADGG:51 datasheet, 74LVCH16541ADGG:51 pinout, 74LVCH16541ADGG:51 application, or 74LVCH16541ADGG:51 equivalent, key selection criteria include its 5 V-tolerant inputs/outputs, bus hold on all data inputs, low propagation delay (as low as 1.0 ns at 3.0–3.6 V), and TSSOP48 package with 48-pin flow-through pinout optimized for PCB routing.
Technical Context
This device implements two independent 8-bit buffer sections (1A→1Y and 2A→2Y), each controlled by two active-low output enable inputs (nOE1/nOE2) enabling fine-grained 3-state control per byte group. The bus hold circuit maintains valid logic states on unused inputs without external pull-ups, reducing BOM count and board space.
It complies with JEDEC standards JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V), and features ESD protection exceeding 2000 V HBM, 200 V MM, and 1000 V CDM - critical for industrial and computing environments with frequent handling or noisy signal paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16244ADGGR | Same 16-bit non-inverting 3-state buffer, but lacks bus hold; requires external pull resistors on unused inputs. | Suitable for cost-sensitive designs where bus hold is not required and board space allows pull resistors. | Select when lower unit cost outweighs added BOM complexity and reliability risk from floating inputs. |
| 74ALVC164245PW | Bidirectional 16-bit transceiver with auto-direction control; supports true 3.3 V ↔ 5 V level translation (not just tolerance). | Required for applications needing bidirectional data flow (e.g., shared memory bus) with automatic direction sensing. | Choose only if bidirectional operation and true level shifting are mandatory - not a drop-in replacement for unidirectional buffering. |
Compared with SN74LVC16244ADGGR and 74ALVC164245PW, the 74LVCH16541ADGG:51 uniquely combines bus hold, 5 V-tolerant I/O, and flow-through pinout in a single TSSOP48 package - delivering higher integration, lower layout risk, and improved robustness for unidirectional bus isolation in mixed-voltage systems.

FAQ
What is the maximum supply voltage for 74LVCH16541ADGG:51?
The absolute maximum supply voltage (VCC) for 74LVCH16541ADGG:51 is +6.5 V, but the recommended operating range is 1.2 V to 3.6 V. Operation outside this range may cause permanent damage or unpredictable behavior. For reliable function, maintain VCC within 1.2 V–3.6 V while leveraging its 5.5 V-tolerant I/O capability for interfacing with higher-voltage logic.
Does 74LVCH16541ADGG:51 support hot insertion or live bus connection?
Yes, 74LVCH16541ADGG:51 supports hot insertion due to its 5 V-tolerant outputs (up to 5.5 V when disabled) and high-impedance outputs when VCC = 0 V. This allows safe connection to a live 5 V bus even before the device's VCC rail is powered, preventing back-driving and latch-up - critical for modular backplane and field-replaceable unit designs.
How does the bus hold feature work on 74LVCH16541ADGG:51?
The bus hold circuit on 74LVCH16541ADGG:51 actively maintains the last-valid logic state on all data inputs (1A[0:7], 2A[0:7]) using weak feedback transistors. It provides ±10 µA to ±75 µA holding current depending on VCC, eliminating the need for external pull-up or pull-down resistors - reducing component count and improving reliability in systems with unterminated or intermittently connected inputs.
Can 74LVCH16541ADGG:51 be used in automotive applications?
Yes, 74LVCH16541ADGG:51 is qualified for operation from −40 °C to +125 °C and meets stringent ESD requirements (HBM > 2000 V), making it suitable for non-safety-critical automotive applications such as body control modules, infotainment interfaces, and lighting drivers - provided it is not deployed in ASIL-B or higher safety domains without additional system-level validation.
What is the pin compatibility between 74LVCH16541ADGG:51 and 74LVCH16541ADL?
74LVCH16541ADGG:51 (TSSOP48, SOT362-1) and 74LVCH16541ADL (SSOP48, SOT370-1) share identical pin functions and logic behavior but differ in physical package: TSSOP has 6.1 mm body width and 0.5 mm pitch, while SSOP has 7.5 mm body width and 0.635 mm pitch. They are not mechanically interchangeable - PCB layout must match the specific package footprint.
