Product details

Overview

74LVC257APW/C5J from NXP Semiconductors is a quad 2-input multiplexer with 3-state outputs, operating from 1.65 V to 3.6 V supply, featuring 4.8 ns typical propagation delay at 3.3 V, ±24 mA output drive, and CMOS-compatible inputs. It routes one of two data inputs per channel to a common output under select control, used in digital logic interfacing and bus multiplexing in industrial control modules.

For engineers reviewing the 74LVC257APW/C5J datasheet, 74LVC257APW/C5J pinout, 74LVC257APW/C5J application, or 74LVC257APW/C5J equivalent, key selection criteria include voltage compatibility with 3.3 V LVC logic families, 3-state output timing behavior, channel-to-channel skew tolerance, and thermal performance in TSSOP-16 packages.

Technical Context

This device implements four independent 2:1 multiplexers sharing common select (S) and output enable (E̅) controls. Each channel performs bitwise selection between I0 and I1 inputs based on S, with outputs placed in high-impedance state when E̅ is high. Logic thresholds are referenced to V_CC, supporting mixed-voltage interface operation.

Propagation delays are specified over full V_CC range (1.65–3.6 V) and temperature (−40°C to +125°C), with output transition times tightly controlled to minimize bus contention during state changes. Input hysteresis ensures noise immunity on select and enable lines.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	1.65 V to 3.6 V - enables direct interface with 1.8 V, 2.5 V, and 3.3 V logic systems without level shifters.
Propagation Delay	4.8 ns (typ) at V_CC = 3.3 V - supports 100+ MHz bus switching in synchronous logic designs.
Output Drive	±24 mA at V_CC = 3.3 V - drives standard LVC loads across full temperature range without derating.
Input Hysteresis	≈150 mV - suppresses false switching from slow-rising or noisy control signals on S and E̅ pins.
Power Dissipation	10 µA max I_CC (standby) - maintains low static power in battery-backed or always-on subsystems.
ESD Rating	HBM ±2000 V - meets IEC 61000-4-2 Level 2 for board-level robustness in industrial environments.

Pinout & Package

TSSOP-16 package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, lead-free, RoHS-compliant, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
1, 4, 9, 12	Data Input I0	First input per multiplexer channel; tied low or driven by upstream logic source.
2, 5, 10, 13	Data Input I1	Second input per channel; enables dual-source selection per bit lane.
3, 6, 11, 14	Output Y	Active-high 3-state output; high-impedance when E̅ = HIGH.
7	GND	Ground reference for all internal logic and I/O structures.
16	V_CC	Primary supply rail; must be decoupled within 10 mm of pin with ≥100 nF ceramic capacitor.
15	E̅	Active-low output enable; asserts all Y outputs simultaneously when LOW.
8	S	Common select line; determines whether I0 or I1 is routed to each Y output.

Key Features

Feature	Design Value
Wide Supply Range	Operates across 1.65–3.6 V, enabling reuse across multiple voltage domains in mixed-signal PCBs.
Simultaneous Channel Enable	Single E̅ pin controls all four outputs, simplifying bus arbitration logic and reducing GPIO count.
Controlled Output Transitions	Specified t_PLH/t_PHL ≤ 7.5 ns ensures predictable setup/hold timing margins in synchronous bus interfaces.
IOFF Protection	Prevents current backflow when V_CC = 0 V, allowing safe live insertion into powered-backplane systems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad 2:1 multiplexer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC257APWR	Same logic function and pinout; differs in packaging (TSSOP-16 vs. PW package code), tape-and-reel quantity, and moisture sensitivity level (MSL 1 vs. MSL 3).	Identical electrical behavior; suitable for drop-in replacement where packaging and handling requirements align.	Select when sourcing from TI distribution channels or requiring alternate reel configuration.
74LVCH257APW	Includes bus-hold circuitry on all inputs; higher ICC (max 40 µA) and slightly longer t_PD (5.5 ns typ at 3.3 V).	Eliminates need for external pull-ups on floating inputs; adds ~0.5 ns jitter in critical timing paths.	Choose when system has unconnected inputs during power-up or hot-swap scenarios.

Compared with SN74LVC257APWR, the 74LVC257APW/C5J offers identical functionality with NXP-specific qualification and traceability; versus 74LVCH257APW, it trades bus-hold protection for lower static current and tighter propagation delay control.

FAQ

What is the maximum clock frequency supported by 74LVC257APW/C5J?

The device does not operate on a clock signal-it is combinatorial logic. Its usable switching rate is determined by propagation delay (4.8 ns typ) and system timing margins. At 3.3 V, it reliably supports data rates up to 100 MHz in bus-multiplexed configurations with proper PCB layout and termination.

Can 74LVC257APW/C5J interface directly with 5 V TTL logic?

No. Its absolute maximum input voltage is V_CC + 0.5 V, and it lacks 5 V-tolerant inputs. Direct connection to 5 V logic risks damage or undefined operation. A level-shifter such as NXP's NXSA3003 or discrete resistor-divider network is required for safe interfacing.

Is the 74LVC257APW/C5J pin-compatible with older 74HC257 devices?

No. While both are quad 2:1 multiplexers, 74HC257 uses different pin assignments (e.g., separate enable per channel) and operates at 2–6 V. The 74LVC257APW/C5J has unified E̅ and S pins and requires 1.65–3.6 V-direct substitution will cause functional failure.

Does 74LVC257APW/C5J support partial power-down operation?

Yes. Its IOFF specification guarantees that no current flows between powered and unpowered sections when V_CC = 0 V, enabling hot-plug capability in backplane or modular systems where this IC may be inserted into an already-powered slot.
