Product details

Overview

74LVT16244BDGG,512 from Nexperia is a 3.3 V 16-bit non-inverting buffer/driver with 3-state outputs, designed for high-speed bus interface applications in industrial and telecom systems. It features four independent output-enable inputs (1OE–4OE), ±32 mA/±64 mA drive capability, overvoltage-tolerant inputs up to 5.5 V, and bus-hold circuitry eliminating external pull-up resistors.

For engineers reviewing the 74LVT16244BDGG,512 datasheet, 74LVT16244BDGG,512 pinout, 74LVT16244BDGG,512 application, or 74LVT16244BDGG,512 equivalent, key selection criteria include 3-state timing (tPZH ≤ 4.0 ns), wide supply range (2.7–3.6 V), I_OFF power-down operation, and TSSOP48 package compatibility with dense PCB layouts.

Technical Context

This BiCMOS device implements four independent 4-bit buffer sections, each controlled by a dedicated active-low output enable (nOE). Each section drives four outputs with rail-to-rail logic swing and supports live insertion due to I_OFF protection and bus-hold on all data inputs.

Input clamping tolerates −0.5 V to +7.0 V, enabling safe interfacing with 5 V TTL buses without level shifters. Propagation delays are tightly specified: t_PLH/t_PHL ≤ 3.2 ns at V_CC = 3.0–3.6 V, and 3-state enable/disable times (t_PZH, t_PLZ) are ≤ 4.5 ns, supporting high-frequency bus arbitration.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	2.7 V to 3.6 V - ensures stable operation across noisy industrial rails and battery-backed 3.3 V domains
Output Drive	+64 mA sink / −32 mA source - drives heavy capacitive loads (e.g., 50 pF buses) without signal degradation
Input Voltage Range	0 V to 5.5 V - enables direct connection to legacy 5 V TTL logic without external level translation
Propagation Delay	≤ 3.2 ns (V_CC = 3.0–3.6 V) - supports >200 MHz bus clocking with deterministic timing margins
Bus Hold Current	±75 μA to ±135 μA - actively holds unused inputs at valid logic levels, removing need for 10 kΩ pull-ups
3-State Leakage	±5 μA max (V_O = 5.5 V) - prevents false triggering when outputs float onto powered 5 V backplanes
Operating Temperature	−40 °C to +85 °C - qualified for extended industrial environments including base station and factory automation

Pinout & Package

TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm pitch - optimized for automated SMT assembly and thermal dissipation in compact modules.

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE, 3OE, 4OE (pins 1, 48, 25, 24)	Active-low output enable	Individually gates four 4-bit output groups; HIGH forces high-impedance state to isolate bus segments
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 feature bus-hold circuitry - eliminates floating inputs and reduces BOM count
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)	Buffered outputs	Non-inverting, 3-state, capable of driving ±32 mA/±64 mA - supports hot-swap and multi-drop bus topologies
V_CC (pins 7, 18, 31, 42)	Power supply	Four distributed V_CC pins reduce IR drop and improve noise immunity across 16-bit path
GND (pins 4, 10, 15, 21, 28, 34, 39, 45)	Ground reference	Eight GND pins minimize ground bounce and support clean signal integrity for high-speed switching

Key Features

Feature	Design Value
Independent 4-channel 3-state control	Four OE pins allow granular bus segmentation - e.g., isolate memory, peripheral, and debug interfaces simultaneously
Overvoltage-tolerant inputs	Withstands 5.5 V input while powered from 3.3 V - enables mixed-voltage system integration without translators
IOFF partial power-down	Outputs enter high-Z state during power ramp-up/down - prevents back-driving and latch-up during sequencing
Live insertion support	IOFF + bus hold + ESD protection (HBM >2000 V) permits hot-plug into live backplanes
BiCMOS process	Combines bipolar speed and CMOS low static power - achieves <3.2 ns delay with <0.12 mA ICC supply current

Applications

Memory Interface Buffering

Industrial Backplane Driver

Use Scenario: Driving address/data lines between FPGA and parallel NOR flash in programmable logic controllers.

IC Role / Device Role / Timing Role: Non-inverting 16-bit buffer with per-group 3-state control synchronizes read/write strobes and isolates flash during configuration.

Use Value: Bus hold maintains valid address states during FPGA reconfiguration; 3.2 ns propagation ensures setup/hold compliance at 100 MHz bus clocks.

Use Scenario: Interfacing multiple MCU modules to a shared 16-bit VMEbus-compatible backplane in factory automation racks.

IC Role / Device Role / Timing Role: Level-shifting bus driver with 5.5 V tolerant inputs connects 3.3 V MCUs to legacy 5 V backplane signaling.

Use Value: Eliminates discrete level shifters; ±64 mA drive sustains signal integrity across 30 cm backplane traces loaded with 10+ slots.

Telecom Line Card Interface

Test Equipment Signal Conditioning

Use Scenario: Isolating and buffering control signals (reset, interrupt, config) between baseband processor and RF transceiver on 5G small cell line cards.

IC Role / Device Role / Timing Role: Four independent OE-controlled buffers manage signal routing across voltage-isolated domains with precise timing alignment.

Use Value: Independent OE pins enable dynamic reconfiguration of signal paths; t_PZH ≤ 4.0 ns guarantees interrupt latency <5 ns under worst-case conditions.

Use Scenario: Driving DUT (device-under-test) inputs in automated test equipment where signal integrity and channel isolation are critical.

IC Role / Device Role / Timing Role: Precision 16-bit driver with matched propagation delay and low skew delivers synchronized stimulus vectors to ASICs/FPGAs.

Use Value: 0.5 ns typical t_PLH/t_PHL skew ensures <100 ps inter-channel timing mismatch; 8 GND pins suppress crosstalk in high-density test fixtures.

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
SN74LVC16244ADGGR	Lower drive (±24 mA), narrower V_CC range (1.65–3.6 V), no bus hold	Requires external pull-ups; unsuitable for 5 V-tolerant mixed-voltage designs	Select only if cost-sensitive and system uses only 3.3 V logic with no floating inputs
74ALVCH16244DGG,118	Higher speed (t_PD ≤ 2.8 ns), same V_CC range, but no overvoltage tolerance (max VI = V_CC + 0.3 V)	Cannot interface directly with 5 V buses; requires level shifters in mixed-voltage systems	Choose when maximum speed is critical and all connected logic is strictly 3.3 V

Compared with SN74LVC16244ADGGR and 74ALVCH16244DGG,118, the 74LVT16244BDGG,512 uniquely combines 5.5 V input tolerance, bus hold, and ±64 mA drive - making it the only option for robust 3.3 V/5 V hybrid bus interfaces requiring zero external components.

FAQ

What is the maximum input voltage the 74LVT16244BDGG,512 can tolerate?

The device accepts input voltages from −0.5 V to +7.0 V, with guaranteed overvoltage tolerance up to +5.5 V regardless of V_CC level. This allows direct interfacing with 5 V TTL buses while operating from a 3.3 V supply, eliminating level-shifter ICs or resistive dividers in mixed-voltage designs.

Does the 74LVT16244BDGG,512 require external pull-up resistors on unused inputs?

No. All data inputs feature integrated bus-hold circuitry that actively maintains the last-valid logic state with ±75 μA to ±135 μA holding current. This eliminates the need for external pull-up or pull-down resistors, reducing BOM count and PCB area in high-pin-count applications.

How does the IOFF circuit function during power sequencing?

When V_CC drops below 1.2 V, the IOFF circuit disables output drivers and places all Y outputs in high-impedance state - preventing back-current flow into powered bus segments. This protects downstream devices during hot-insertion, power-up, or brown-out conditions without requiring external control logic.

Can the 74LVT16244BDGG,512 be used in automotive applications?

No. The 74LVT16244BDGG,512 is not AEC-Q100 qualified and is specified only for industrial temperature range (−40 °C to +85 °C). Nexperia explicitly states non-automotive qualification in its legal disclaimers; use in safety-critical or automotive systems is unsupported and carries no warranty or reliability guarantee.
