Product details

Overview

74ALVT16827DGGY from Nexperia is a 20-bit non-inverting 3-state buffer/line driver in TSSOP56 (SOT364-1) package, operating from 2.3 V to 3.6 V supply. It supports dual 10-bit or unified 20-bit bus buffering with independent active-low output enables (1OE0/1OE1/2OE0/2OE1), bus hold on all data inputs, and overvoltage-tolerant inputs up to 5.5 V. Used in high-speed digital backplanes and memory interface expansion.

For engineers reviewing the 74ALVT16827DGGY datasheet, 74ALVT16827DGGY pinout, 74ALVT16827DGGY application, or 74ALVT16827DGGY equivalent, key selection criteria include 3-state timing (tPZH ≤ 3.8 ns @ 3.3 V), bus hold current (IBHL = 75–130 μA), IOFF power-down leakage (< ±100 μA), and compatibility with TTL-level drivers and 5 V buses without external pull-ups.

Technical Context

The device implements two independent 10-bit non-inverting buffer sections, each controlled by dedicated active-low enable inputs (1OE0/1OE1 for Group 1; 2OE0/2OE1 for Group 2). A HIGH on any enable input forces its associated 10 outputs into high-impedance OFF-state.

Its BiCMOS architecture delivers TTL-compatible output drive (IOL = 64 mA @ 3.3 V) while maintaining low static current (ICC ≤ 0.1 mA) and supporting hot-swap-safe IOFF circuitry. Bus hold eliminates external biasing for unused inputs, and overvoltage tolerance allows direct interfacing with 5 V logic despite 2.3–3.6 V core operation.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	2.3 V to 3.6 V - Enables interoperability with both 2.5 V and 3.3 V systems without level shifters
Input voltage tolerance	Up to 5.5 V - Allows safe connection to legacy 5 V buses without damage or clamping diodes
Propagation delay (tPLH/tPHL)	0.7–2.3 ns @ 3.3 V - Supports >400 MHz bus toggle rates in point-to-point configurations
Output drive (IOL/IOH)	64 mA / 32 mA @ 3.3 V - Drives 10+ LVTTL loads or terminates stubs on medium-length traces
Bus hold current	IBHL = 75–130 μA, IBHH = −75 to −140 μA - Maintains valid logic state on floating inputs without external resistors
IOFF leakage	< ±100 μA @ VCC = 0 V - Prevents back-driving and signal corruption during partial power-down
Operating temperature	−40 °C to +85 °C - Qualified for industrial-grade embedded control and communications equipment

Pinout & Package

TSSOP56 (SOT364-1) package: plastic thin shrink small outline, 56 leads, 6.1 mm body width, 0.5 mm pitch, 1.2 mm max height. Pin 1 index marked; lead finish: SnAgCu (lead-free).

Pin/Terminal	Circuit Role	Design Meaning
1OE0, 1OE1, 2OE0, 2OE1	Active-low output enable	Each pair controls 10 outputs; HIGH disables corresponding group, enabling independent bus segmentation
1A0–1A9, 2A0–2A9	Data input	20 total inputs with bus hold; tolerate 5.5 V regardless of VCC, simplifying mixed-voltage board design
1Y0–1Y9, 2Y0–2Y9	Data output	Non-inverting, 3-state outputs; support hot insertion and bidirectional bus arbitration when paired with complementary devices
VCC (pins 7, 22, 35, 50)	Power supply	Four distributed VCC pins reduce switching noise and improve PSRR across wide-frequency digital activity
GND (pins 4, 11, 18, 25, 32, 39, 46, 53)	Ground reference	Eight GND pins provide low-inductance return paths, critical for clean 3-state transitions and EMI control

Key Features

Feature	Design Value
Wide supply range	2.3 V–3.6 V operation ensures compatibility with both 2.5 V and 3.3 V FPGA I/O banks and ASIC interfaces
Overvoltage-tolerant inputs	5.5 V absolute max rating enables direct connection to 5 V peripherals without external protection or translation
Bus hold circuitry	Eliminates need for 10 kΩ pull-up/down resistors on unused inputs-reducing BOM count and PCB area
IOFF partial power-down	Prevents current flow through powered-off sections when VCC = 0 V, essential for hot-plug and modular system designs
Latch-up immunity	Exceeds JESD78 Class II Level B (500 mA), ensuring robustness against transient-induced latch-up in noisy environments

Applications

Memory Interface Expansion

Industrial Backplane Buffering

Use Scenario: Extending address/data bus width between microcontroller and parallel NOR flash or SRAM.

IC Role / Device Role / Timing Role: Non-inverting 20-bit buffer with independent 10-bit enables isolates memory banks and reduces capacitive loading on MCU pins.

Use Value: Propagation delay ≤ 2.3 ns and 64 mA drive ensure setup/hold timing margins are maintained at 100 MHz bus clock.

Use Scenario: Driving long, multi-drop control lines (e.g., reset, interrupt, chip select) across 150 mm PCB backplane.

IC Role / Device Role / Timing Role: Line driver with bus hold maintains signal integrity and prevents floating states during hot-swap events.

Use Value: Overvoltage-tolerant inputs survive 5 V transients; IOFF prevents backfeed when slot power is removed mid-operation.

FPGA I/O Voltage Translation

Legacy System Bus Isolation

Use Scenario: Interfacing 3.3 V FPGA bank to 2.5 V peripheral logic without discrete level shifters.

IC Role / Device Role / Timing Role: Bidirectional-capable buffer (with external direction control) translates voltage thresholds while preserving timing.

Use Value: VIH/VIL specs (2.0 V/0.8 V @ 3.3 V) meet 2.5 V logic thresholds; tPLH/tPHL variation < 0.5 ns ensures skew-controlled routing.

Use Scenario: Isolating aging ISA or PCI bus segments from modern controller logic in test equipment upgrades.

IC Role / Device Role / Timing Role: 3-state buffer decouples legacy bus capacitance and enables software-controlled segment enable/disable.

Use Value: Independent OE pins allow selective activation of 10-bit groups; bus hold prevents glitches during configuration changes.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 20-bit non-inverting buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74ALVTH16827DGGR	TI part in same TSSOP56 package; identical pinout; slightly higher ICC (0.2 mA vs 0.1 mA) and lower VOL (0.35 V vs 0.4 V @ 3.3 V/64 mA)	Same industrial temperature range; marginally better drive strength but higher quiescent current	Preferred where tighter VOL spec is required for noise margin; verify thermal derating with TI's thermal resistance data
74LVT16827DGG	Nexperia LVT variant; same footprint; lacks bus hold and IOFF; operates only down to 2.7 V (not 2.3 V)	Not suitable for partial-power-down or floating-input scenarios; limited to 3.3 V-only systems	Select only if bus hold and IOFF are unnecessary and supply is strictly regulated at 3.3 V ±3%

Compared with SN74ALVTH16827DGGR, the 74ALVT16827DGGY offers lower ICC and integrated bus hold, reducing external components; versus 74LVT16827DGG, it adds critical low-voltage operation and power-down safety-making it superior for mixed-voltage and hot-swap designs.

FAQ

Does 74ALVT16827DGGY support hot-swap insertion?

Yes. Its IOFF circuitry ensures that when VCC = 0 V, the inputs and outputs present less than ±100 μA leakage, preventing back-driving of live buses. Combined with overvoltage-tolerant inputs (up to 5.5 V), this enables safe insertion into powered-backplane systems without risk of latch-up or damage.

Can unused inputs be left floating?

Yes. All 20 data inputs feature integrated bus hold circuitry, which actively maintains the last-valid logic state without external pull-up or pull-down resistors. This eliminates floating-node uncertainty and reduces BOM cost and layout complexity-verified across −40 °C to +85 °C.

What is the maximum clock frequency supported for toggling all 20 outputs?

Based on worst-case propagation delay (tPLH/tPHL ≤ 2.3 ns @ 3.3 V) and output transition time (tr/tf ≤ 2.5 ns), the device supports reliable 200 MHz sustained toggling in point-to-point configurations. For multi-load buses, derate based on measured load capacitance and termination-Nexperia specifies CL = 50 pF in timing tests.

How does the dual-enable architecture improve system design?

The four active-low enables (1OE0/1OE1/2OE0/2OE1) allow independent control of two 10-bit groups. This enables dynamic bus segmentation-e.g., enabling only memory address lines while holding data lines in high-Z during DMA cycles-reducing crosstalk, power spikes, and contention in complex multi-peripheral systems.
