Product details

Overview

74ALVC16240MTD from Fairchild Semiconductor is a low-voltage 16-bit inverting buffer/line driver with 3.6V-tolerant I/O, designed for memory/address bus driving and clock distribution in 1.65V–3.6V systems. It features nibble-level 3-STATE control (four independent OE inputs), 3.0 ns max propagation delay at 3.3V, and power-off high-impedance protection.

For engineers reviewing the 74ALVC16240MTD datasheet, pinout, applications, or equivalent options, key selection criteria include 3.6V I/O tolerance, 4-channel independent 3-STATE enable, inverting logic function, and TSSOP-48 package compatibility with high-density PCB layouts.

Technical Context

The 74ALVC16240MTD implements sixteen identical inverting buffers grouped into four independent 4-bit nibbles, each controlled by its own active-low Output Enable (OEn) input. All inputs and outputs tolerate up to 3.6V regardless of VCC level (1.65V–3.6V), enabling mixed-voltage interfacing without level shifters.

It uses advanced CMOS process technology to achieve sub-4 ns propagation delay while maintaining low static current (40 µA typical ICC at 3.6V) and supports live insertion via power-off high-Z behavior. Latchup immunity complies with JEDEC JED78 and ESD withstands 2000V HBM.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	1.65V to 3.6V - enables operation across multiple low-voltage logic families including 1.8V, 2.5V, and 3.3V systems
I/O Voltage Tolerance	Up to 3.6V - allows safe interfacing with higher-voltage peripherals without external clamping or translation
tPD (Max)	3.0 ns at VCC = 3.3V - supports high-speed address/data bus timing in memory and FPGA interface applications
3-STATE Control	Four independent OEn pins (OE1–OE4) - permits selective 4-bit nibble gating for partial bus isolation
IOH/IOL Drive	±24 mA at VCC ≥ 2.3V - sufficient to drive 50 pF loads with fast edge rates and minimal signal degradation
Power-off High-Z	Inputs and outputs enter high-impedance state when VCC = 0V - prevents back-driving during hot-swap or power sequencing

Pinout & Package

74ALVC16240MTD is housed in a 48-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153 compliant, 6.1 mm wide, with 0.5 mm lead pitch. Thermal and mechanical data align with standard TSSOP-48 footprint requirements.

Pin/Terminal	Circuit Role	Design Meaning
OEn (OE1–OE4)	Active-low 3-STATE enable per nibble	Each controls 4 outputs (e.g., OE1 → O0–O3); shorting enables full 16-bit operation
I0–I15	Inverting buffer inputs	16 logic inputs accepting 0V–3.6V; internally pulled to VCC/GND not required due to defined VIH/VIL thresholds
O0–O15	Inverting buffer outputs	16 CMOS outputs with 3-STATE capability; output polarity inverted relative to corresponding input
VCC, GND	Power supply pins	Two VCC (pins 24, 48) and two GND (pins 12, 36) for reduced supply noise and improved signal integrity

Key Features

Feature	Design Value
Nibble-selectable 3-STATE control	Four independent OE inputs allow dynamic partitioning of 16-bit bus into four isolated 4-bit segments
3.6V-tolerant I/O on 1.65V–3.6V supply	Eliminates need for external voltage translators when interfacing with legacy 3.3V or 5V peripherals
Propagation delay ≤3.0 ns at 3.3V	Meets timing budgets for DDR memory address latching and FPGA-to-ASIC clock fanout
Power-off high-impedance protection	Prevents current leakage or bus contention during power-up/down sequences in modular systems

74LVC16240APAG	Same logic function and 3.6V I/O, but operates down to 1.65V; differs in AC characteristics - 3.8 ns max tPD at 3.3V vs. 3.0 ns for 74ALVC16240MTD	Suitable for lower-speed interfaces where <3 ns delay is not required; slightly higher ICC at 3.3V	Select when cost sensitivity outweighs 0.8 ns timing margin; verify tPD compliance in critical paths

Compared with SN74ALVC16240DGGR and 74LVC16240APAG, the 74ALVC16240MTD delivers the fastest propagation delay (3.0 ns) within its voltage range and maintains strict JEDEC-compliant timing across all four nibbles - making it optimal for high-speed synchronous bus applications requiring deterministic latency.

Manufacturer

Fairchild Semiconductor was a leading designer of high-performance analog and mixed-signal ICs, acquired by ON Semiconductor in 2016; its legacy logic portfolio remains widely deployed in industrial and computing infrastructure.

The ALVC (Advanced Low-Voltage CMOS) family, including the 74ALVC16240MTD, was engineered for high-speed, low-power 16-bit bus interface applications in portable, embedded, and telecom equipment operating from 1.65V to 3.6V.

FAQ

What is the maximum propagation delay of the 74ALVC16240MTD at 3.3V supply?

The 74ALVC16240MTD has a maximum propagation delay (tPD) of 3.0 ns when VCC = 3.3V ±0.3V, measured under CL = 50 pF load conditions. This value is specified across the full commercial temperature range (–40°C to +85°C) and ensures timing compliance in high-speed memory and clock distribution circuits where sub-4 ns latency is critical.

Does the 74ALVC16240MTD support live insertion and hot-swap operations?

Yes, the 74ALVC16240MTD supports live insertion and withdrawal per Note 1 in the datasheet. Its power-off high-impedance behavior ensures inputs and outputs enter a high-Z state when VCC = 0V, preventing bus contention. For robust operation during power-up/down, OE should be tied to VCC via a pull-up resistor, as specified in the application note.

How many independent 3-STATE control inputs does the 74ALVC16240MTD have?

The 74ALVC16240MTD has four independent active-low Output Enable inputs (OE1–OE4), each controlling a 4-bit nibble (I0–I3/O0–O3, etc.). This architecture allows selective 3-STATE control of any 4-bit segment of the 16-bit bus - enabling flexible bus partitioning without requiring external logic or multiplexers.

What is the I/O voltage tolerance specification for the 74ALVC16240MTD?

The 74ALVC16240MTD guarantees 3.6V-tolerant inputs and outputs across its entire 1.65V–3.6V VCC operating range. This means I/O pins can safely accept and drive signals up to 3.6V even when powered at 1.8V or 2.5V, eliminating the need for external level-shifting components in mixed-voltage system designs.

Is the 74ALVC16240MTD pin-compatible with other 16-bit ALVC buffer variants?

Yes, the 74ALVC16240MTD shares the same TSSOP-48 (MTD48) pinout and electrical interface as other members of the ALVC16240 family, including non-inverting variants like 74ALVC16244MTD. However, logic inversion is inherent to the 74ALVC16240MTD - substituting it for a non-inverting buffer requires complementary logic inversion elsewhere in the signal path.
