Product details
Overview
74ALVC16827MTDX from Fairchild Semiconductor is a low-voltage 20-bit non-inverting buffer/line driver with 3-STATE outputs, byte-level NOR output enables (OE1–OE4), 3.6V-tolerant I/O, and propagation delay as low as 3.0 ns at 3.3V - used in memory address buffering, clock distribution, and bus transceiver applications requiring voltage translation between 1.65V–3.6V domains.
For engineers reviewing the 74ALVC16827MTDX datasheet, pinout, applications, or equivalent options, key selection criteria include 3.6V I/O tolerance, byte-wise 3-STATE control, sub-4 ns propagation delay across VCC range, and TSSOP-56 packaging for high-density PCB layouts.
Technical Context
The 74ALVC16827MTDX implements twenty independent non-inverting buffers partitioned into two 10-bit bytes, each controlled by dual active-low NOR enables (OE1/OE2 for bits 0–9; OE3/OE4 for bits 10–19). Outputs enter high-impedance state when either enable in a pair is HIGH.
It operates from 1.65V to 3.6V VCC while maintaining full 3.6V tolerance on all inputs and outputs - enabling safe interfacing with higher-voltage logic without level shifters. Its advanced CMOS process delivers low dynamic power (CPD = 20 pF) and supports live insertion via power-off high-impedance I/O behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 3.6V - supports mixed-voltage system integration including 1.8V, 2.5V, and 3.3V domains |
| I/O Voltage Tolerance | Up to 3.6V - allows direct connection to legacy 3.3V or 5V-tolerant systems without external clamping |
| tPD (Max) | 3.0 ns @ 3.3V - ensures timing-critical clock and address path integrity in high-speed memory interfaces |
| IOH/IOL Drive | ±24 mA @ 3.0V - sufficient to drive 50Ω transmission lines or multiple CMOS loads |
| Power-off High-Z | Inputs and outputs float to high impedance when VCC = 0V - enables hot-swap capability in backplane applications |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade embedded and computing environments |
Pinout & Package
74ALVC16827MTDX is housed in a 56-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153 compliant, 6.1 mm wide, with 0.5 mm lead pitch - optimized for automated assembly and thermal performance in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OEn (OE1–OE4) | Byte-select 3-STATE enable (active LOW) | Each pair controls 10-bit output group; NOR logic allows flexible byte or full-device gating |
| I0–I19 | Buffer input terminals | 20 single-ended CMOS-compatible inputs with 3.6V tolerance and ±5 µA leakage max |
| O0–O19 | Non-inverting 3-STATE buffer outputs | Drive strength up to ±24 mA; high-impedance state entered within 9.8 ns of OE transition |
| VCC, GND | Power supply pins | Dual VCC/GND pairs (pins 1/28 and 29/56) reduce switching noise and improve PSRR |
Key Features
| Feature | Design Value |
|---|---|
| Byte-wise 3-STATE control | Independent OE1/OE2 and OE3/OE4 allow selective disabling of upper/lower 10-bit segments without affecting data flow in other bytes |
| 3.6V-tolerant I/O | Enables interoperability with 3.3V systems and legacy peripherals without level-shifting circuitry or external protection diodes |
| Live insertion support | Power-off high-impedance I/O prevents bus contention during hot-plug events in modular backplane or card-edge systems |
| Noise/EMI reduction circuitry | Patented edge-rate control minimizes simultaneous switching noise (SSN) in dense memory and address bus layouts |
Applications
| Memory Address Buffering | Clock Distribution Network |
|---|---|
Use Scenario: Driving 20-bit address buses between low-voltage microcontrollers and SRAM/Flash devices operating at 1.8V or 2.5V. IC Role / Device Role / Timing Role: Non-inverting buffer with 3-STATE outputs isolates controller from memory load; byte enables allow partial bus gating during page-mode access. Use Value: 3.0 ns tPD ensures setup/hold timing margins are preserved across temperature and voltage corners. | Use Scenario: Distributing a single clock signal to multiple synchronous peripherals (e.g., ADCs, DACs, FPGAs) in mixed-voltage systems. IC Role / Device Role / Timing Role: Low-skew, non-inverting line driver with matched propagation delays across all 20 outputs. Use Value: Sub-4 ns delay variation enables tight skew control (<1 ns typical) for multi-device synchronization. |
| Bus Transceiver Interface | Hot-Swappable Backplane Module |
Use Scenario: Bidirectional data bus isolation between 1.8V SoC and 3.3V peripheral ASICs using external direction control. IC Role / Device Role / Timing Role: Unidirectional buffer configured as half of a transceiver pair; 3.6V I/O tolerance eliminates need for discrete clamps. Use Value: ±24 mA drive strength supports stubbed bus topologies with up to 5 cm trace length at 100 MHz. | Use Scenario: Signal conditioning for hot-pluggable mezzanine cards in industrial PLC chassis with powered backplanes. IC Role / Device Role / Timing Role: Input/output buffer providing power-fail-safe isolation and ESD-hardened interface to backplane connectors. Use Value: Power-off high-Z behavior prevents bus contention during insertion/removal; >2000V HBM ESD rating protects against handling damage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVC16827DGGR | TSSOP-56 package; identical AC/DC specs and pinout per TI datasheet SLAS274G | Same functional behavior and timing; qualified for automotive AEC-Q100 Grade 2 (−40°C to +105°C) | Select for extended temperature operation or TI-aligned BOMs |
| 74LVC162244APAG | 24-bit, dual 12-bit configuration; no 3.6V I/O tolerance (max VI = VCC + 0.3V); different OE architecture (active-HIGH) | Limited to same-supply-domain buffering; requires external level shifting for 3.3V interface | Select only if higher bit count needed and voltage domain isolation is not required |
Compared with SN74ALVC16827DGGR and 74LVC162244APAG, the 74ALVC16827MTDX uniquely combines 20-bit width, 3.6V I/O tolerance, byte-level NOR enables, and industrial temperature range - making it optimal for voltage-translating memory and clock buses where layout density and interoperability are critical.

FAQ
What is the maximum operating voltage for 74ALVC16827MTDX I/O pins?
The 74ALVC16827MTDX supports 3.6V-tolerant inputs and outputs regardless of VCC level - meaning I/O pins can safely accept and drive signals up to 3.6V even when VCC is as low as 1.65V. This eliminates external level shifters in mixed-voltage designs. Absolute maximum rating is 4.6V, but functional 3.6V tolerance is guaranteed per datasheet DS500697.
How does the byte-wise enable architecture of 74ALVC16827MTDX work?
The 74ALVC16827MTDX divides its 20 outputs into two 10-bit groups: O0–O9 controlled by OE1/OE2 (NOR logic), and O10–O19 controlled by OE3/OE4 (also NOR). When both enables in a pair are LOW, outputs drive; if either is HIGH, that byte enters high-impedance. This allows independent gating of address or data nibbles without affecting adjacent signals.
Does 74ALVC16827MTDX support live insertion in powered backplanes?
Yes - the 74ALVC16827MTDX features power-off high-impedance inputs and outputs, ensuring all I/O pins float to high-Z when VCC = 0V. Combined with >2000V HBM ESD rating and patented noise reduction, this enables safe hot-swap operation in modular backplane systems, provided OE pins are pulled appropriately during power transitions.
What is the typical propagation delay of 74ALVC16827MTDX at 1.8V supply?
At VCC = 1.8V ± 0.15V and CL = 50 pF, the 74ALVC16827MTDX has a maximum propagation delay (tPHL/tPLH) of 6.0 ns per datasheet DS500697. Typical delay is lower - approximately 3.5 ns - but design margins must use the 6.0 ns worst-case value for timing closure in 1.8V systems such as ultra-low-power microcontroller interfaces.
Is 74ALVC16827MTDX pin-compatible with other ALVC-series 20-bit buffers?
Yes - the 74ALVC16827MTDX shares identical pinout, function, and timing with industry-standard equivalents like SN74ALVC16827DGGR (TI) and 74ALVC16827PW, all using TSSOP-56 (MTD56) package. Pin mapping for I/O, OE, VCC, and GND is consistent across these variants, enabling second-source flexibility without PCB redesign.
