Product details

Overview

74ALVT16241DGG,118 from NXP Semiconductors (formerly Philips) is a 16-bit 3-state buffer/driver IC designed for bus interface applications in mixed-voltage systems. It operates at V_CC = 2.5 V or 3.3 V with 5 V-tolerant I/O, features four independent output-enable inputs (1OE–4OE), and delivers ±64 mA/−32 mA drive capability on outputs. It is used in high-speed data bus driving where level translation and bus hold functionality are required.

For engineers reviewing the 74ALVT16241DGG,118 datasheet, 74ALVT16241DGG,118 pinout, 74ALVT16241DGG,118 application, or 74ALVT16241DGG,118 equivalent, this device supports live insertion/extraction, provides bus-hold on all data inputs to eliminate external pull-ups, and meets JESD78 latch-up (>500 mA) and ESD (MIL-STD-883 >2000 V) requirements for industrial-grade reliability.

Technical Context

The 74ALVT16241DGG,118 implements a BiCMOS architecture enabling TTL-compatible input thresholds and 5 V I/O tolerance while operating from 2.5 V or 3.3 V supply rails. Its four independent 3-state control inputs (1OE–4OE) each gate a 4-bit output group, allowing segmented bus control without contention.

Each of the 16 outputs supports high-drive capability (−64 mA sink, +32 mA source at 3.3 V), low propagation delay (1.6 ns typical t_PLH/t_PHL @ 3.3 V), and power-up 3-state behavior. Bus-hold circuitry maintains valid logic states on unused inputs, eliminating external biasing components.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Supply	2.5 V ± 0.2 V or 3.3 V ± 0.3 V - dual-rail compatibility enables integration into legacy 3.3 V and emerging low-power 2.5 V systems.
I/O Voltage Tolerance	Up to 5.5 V - allows direct interfacing with 5 V buses without level shifters or clamping diodes.
Propagation Delay	1.6 ns typical (t_PLH/t_PHL, CL = 50 pF, V_CC = 3.3 V) - supports >300 MHz bus operation in short trace configurations.
Output Drive	−64 mA sink / +32 mA source (V_CC = 3.3 V) - sufficient to drive 50 Ω transmission lines or multiple CMOS/TTL loads.
Bus-Hold Current	±75 µA (V_CC = 3 V) - actively retains logic state on floating inputs, removing need for external pull-up/down resistors.
3-State Enable Time	1.6 ns typical t_PZL (V_CC = 3.3 V) - ensures fast, glitch-free bus arbitration during enable/disable transitions.
Input Capacitance	3 pF (on OE pins) - minimizes loading on control signals and preserves timing margins in high-speed enable paths.

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE, 3OE, 4OE (Pins 1, 48, 25, 24)	Active-low output enable	Each controls 4 outputs (e.g., 1OE enables Y0–Y3); independent gating enables partial bus activation and reduces switching noise.
1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 (Pins 47, 46, 44, 43, 41, 40, 38, 37, 36, 35, 33, 32, 30, 29, 27, 26)	Data inputs	All support bus-hold; tolerate VI up to 5.5 V regardless of V_CC; TTL-level compatible thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V @ 3.3 V).
1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 (Pins 2, 3, 5, 6, 8, 9, 11, 12, 13, 14, 16, 17, 19, 20, 22, 23)	3-state buffered outputs	Drive capability: −64 mA / +32 mA; output voltage swing referenced to V_CC; high-impedance state (Z) when corresponding OE is HIGH.
V_CC (Pins 7, 18, 31, 42)	Power supply	Four dedicated V_CC pins reduce IR drop and improve noise immunity across wide bus; decoupling recommended per pair.
GND (Pins 4, 10, 15, 21, 28, 34, 39, 45)	Ground reference	Eight GND pins provide low-inductance return paths for all 16 outputs and internal logic; essential for signal integrity at high edge rates.

Key Features

Feature	Design Value
5 V-tolerant I/O with 2.5 V/3.3 V core	Enables seamless interconnection between newer low-voltage logic and legacy 5 V subsystems without external level translators.
Independent quad-group 3-state control	Four OE inputs allow selective activation of 4-bit segments-critical for memory-mapped peripheral interfaces and multi-drop bus arbitration.
Integrated bus-hold on all data inputs	Eliminates need for 32 external pull-up resistors in a 16-bit configuration, reducing BOM count, board area, and potential noise sources.
Live insertion/extraction support	Robust ESD/latch-up protection (MIL-STD-883 >2000 V, JESD78 >500 mA) permits hot-plug operation in backplane and modular system designs.
Power-up 3-state behavior	Outputs remain in high-impedance state until V_CC stabilizes above 1.2 V, preventing bus contention during power sequencing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit 3-state buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74ALVTH16241DGGR	TI part; identical 16-bit quad-OE architecture, same 2.5/3.3 V operation and 5 V I/O tolerance; slightly higher max t_PLH (2.5 ns vs. 2.2 ns @ 3.3 V).	Pinout-compatible but requires verification of bus-hold strength (TI specifies ±60 µA vs. NXP's ±75 µA at 3 V).	Select if TI supply chain preference exists; confirm bus-hold margin sufficiency for high-noise automotive test environments.
74LVT16244ADGG,118	NXP variant with inverted OE polarity (active HIGH); otherwise identical pinout, drive strength, and voltage specs.	Requires logic inversion in enable control path; not suitable for direct replacement without firmware/hardware modification.	Choose only when active-HIGH enable signaling is required; verify OE signal polarity alignment in existing PCB layout.

Compared with SN74ALVTH16241DGGR and 74LVT16244ADGG,118, the 74ALVT16241DGG,118 offers superior bus-hold current and tighter propagation delay distribution, making it preferred for noise-critical industrial backplanes and high-reliability memory interfaces where deterministic input retention is mandatory.

FAQ

What supply voltages does the 74ALVT16241DGG,118 support?

The 74ALVT16241DGG,118 operates at either 2.5 V ± 0.2 V or 3.3 V ± 0.3 V. Its I/O pins tolerate up to 5.5 V regardless of V_CC, enabling direct connection to 5 V buses without external level-shifting components. This dual-supply flexibility makes the 74ALVT16241DGG,118 ideal for transitional designs migrating from 5 V to lower-voltage logic domains.

Does the 74ALVT16241DGG,118 require external pull-up resistors on its inputs?

No. The 74ALVT16241DGG,118 integrates bus-hold circuitry on all 16 data inputs (A0–A15), providing ±75 µA holding current at 3 V to maintain valid logic states on floating inputs. This eliminates the need for 32 external pull-up or pull-down resistors, reducing BOM cost, PCB area, and potential noise coupling points in the 74ALVT16241DGG,118-based design.

How many output-enable inputs does the 74ALVT16241DGG,118 have, and how are they assigned?

The 74ALVT16241DGG,118 has four active-low output-enable inputs: 1OE (Pin 1), 2OE (Pin 48), 3OE (Pin 25), and 4OE (Pin 24). Each controls a distinct 4-bit output group: 1OE → Y0–Y3, 2OE → Y4–Y7, 3OE → Y8–Y11, 4OE → Y12–Y15. This segmentation allows precise bus arbitration and reduces simultaneous switching noise compared to single-OE 16-bit buffers.

What is the maximum output drive capability of the 74ALVT16241DGG,118?

At V_CC = 3.3 V, the 74ALVT16241DGG,118 delivers −64 mA sink current (I_OL) and +32 mA source current (I_OH). At V_CC = 2.5 V, it provides −32 mA sink and +64 mA source. These asymmetric drive strengths optimize performance for common bus-loading scenarios where stronger sinking is needed to overcome capacitive loads and termination mismatches in the 74ALVT16241DGG,118 application.

Is the 74ALVT16241DGG,118 suitable for hot-plug applications?

Yes. The 74ALVT16241DGG,118 is explicitly rated for live insertion and extraction. It meets MIL-STD-883 ESD protection (>2000 V) and JESD78 latch-up immunity (>500 mA), making it suitable for modular systems such as industrial backplanes and telecom line cards where field-replaceable modules must be inserted or removed without powering down the host system containing the 74ALVT16241DGG,118.
