Product details

Overview

SN74ALVC16244ADGGR from Texas Instruments is a 16-bit non-inverting buffer/driver with 3-state outputs, designed for 1.65-V to 3.6-V V_CC operation. It features ±24-mA output drive at 3.3 V, 3-ns max propagation delay at 3.3 V, and symmetrical active-low output-enable (OE) inputs. It is used in memory-address drivers, clock distribution networks, and high-density bus transceivers.

For engineers reviewing the SN74ALVC16244ADGGR datasheet, SN74ALVC16244ADGGR pinout, SN74ALVC16244ADGGR application, or SN74ALVC16244ADGGR equivalent, key selection criteria include 48-pin TSSOP package compatibility, 3.3-V logic interface support, 3-state bus isolation capability, and latch-up immunity exceeding 250 mA per JESD 17.

Technical Context

The SN74ALVC16244ADGGR implements four independent 4-bit buffers, each with true (non-inverting) output logic and dedicated active-low OE control. Its architecture supports flexible partitioning as one 16-bit, two 8-bit, or four 4-bit buffers - enabling scalable bus loading management without external logic.

All inputs and outputs are 3.3-V tolerant with rail-to-rail swing, and the device includes robust ESD protection (2000-V HBM, 200-V MM, 1000-V CDM). Input thresholds scale with V_CC, supporting mixed-voltage system interfacing across 1.65–3.6 V supply range.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 3.6 V - enables interoperability with 1.8-V, 2.5-V, and 3.3-V logic families
Max t_pd	3 ns at 3.3 V - supports high-speed address/data buffering in sub-ns timing-critical paths
Output Drive	±24 mA at 3.3 V - drives up to 10 LVTTL loads or 20 ALVC loads without signal degradation
Input Thresholds	V_IH = 2.0 V (min), V_IL = 0.8 V (max) at 3.3 V - ensures noise margin >0.7 V under worst-case conditions
Latch-Up Immunity	>250 mA per JESD 17 - prevents destructive current runaway during transient overvoltage events
ESD Protection	2000-V HBM, 200-V MM, 1000-V CDM - meets industrial-grade reliability requirements
Quiescent Current	40 µA max at 3.6 V - minimizes static power in always-on buffer applications

Pinout & Package

TSSOP-48 (DGG) package: 12.6 mm × 6.2 mm × 1.2 mm body, 0.5-mm lead pitch, gull-wing leads, RoHS-compliant NiPdAu finish, MSL Level-1.

Pin/Terminal	Circuit Role	Design Meaning
1OE–4OE	Active-low output enable	Independent control per 4-bit group; must be pulled high via resistor during power-up to ensure Hi-Z state
1A1–4A4	Data inputs	16 total inputs; true logic - output Yn follows An when corresponding OE is low
1Y1–4Y4	3-state outputs	16 buffered outputs; high-impedance when OE = high; full rail-to-rail swing
V_CC	Power supply	Four dedicated V_CC pins (pins 7, 15, 31, 39) reduce switching noise and improve PSRR
GND	Ground reference	Eight GND pins (pins 4, 10, 18, 27, 34, 42, 45, 47) provide low-inductance return paths for all output groups

Key Features

Feature	Design Value
Widebus™ architecture	Optimized pinout and internal routing for minimal crosstalk and skew across 16-bit buses
Supply voltage scaling	Guaranteed operation from 1.65 V to 3.6 V - supports legacy 3.3-V and modern 1.8-V SoC interfaces
Symmetrical OE control	Four independent active-low OE inputs allow selective 4-bit group isolation without additional logic
High-current drive	±24-mA sink/source at 3.3 V - eliminates need for external bus repeaters in medium-load systems
Power-up Hi-Z guarantee	OE tied to V_CC via pullup ensures outputs remain high-impedance until valid control is applied

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 strength (±24 mA only at 3.3 V; degrades to ±12 mA at 2.5 V); identical pinout and function	Less suitable for mixed-voltage systems operating below 3.0 V due to reduced noise margin and drive	Select when cost sensitivity outweighs performance margin at sub-3-V operation
74ALVC16244PW	TSSOP-48 package same; slightly higher t_pd (3.7 ns typ at 3.3 V vs. 3.0 ns max); identical electrical specs	Same functional use but requires validation of thermal derating in high-density PCB layouts	Choose if existing footprint uses NXP's PW marking convention and board layout tolerates +0.7 ns delay margin

Compared with SN74LVC16244ADGGR and 74ALVC16244PW, the SN74ALVC16244ADGGR delivers tighter propagation delay control (3 ns max vs. 3.7 ns typ), superior sub-3-V drive capability, and TI-specific Widebus™ layout optimization for lower inter-bit skew in high-speed bus applications.

FAQ

What is the maximum operating frequency supported by the SN74ALVC16244ADGGR?

The SN74ALVC16244ADGGR does not specify a maximum clock frequency in its datasheet because it is a combinational buffer, not a clocked device. Its usable frequency limit is determined by propagation delay (3 ns max at 3.3 V) and system-level signal integrity. For clean 100-MHz bus operation, the SN74ALVC16244ADGGR provides sufficient timing margin with typical rise/fall times under 2.5 ns and output capacitance of 7 pF.

Can the SN74ALVC16244ADGGR be used with a 1.8-V supply?

Yes, the SN74ALVC16244ADGGR is fully specified for 1.65-V to 3.6-V operation, including 1.8-V V_CC. At 1.8 V, it delivers ±4 mA output drive, VIH/VIL thresholds scale to 0.65×V_CC and 0.35×V_CC, and t_pd increases to 3.7 ns (typical). The SN74ALVC16244ADGGR maintains full functionality and guaranteed timing across this range without external level shifters.

How should unused inputs be handled on the SN74ALVC16244ADGGR?

All unused inputs on the SN74ALVC16244ADGGR - including data inputs (A1–A4 per group) and OE terminals - must be tied to either V_CC or GND to prevent floating nodes that cause increased ICC, noise coupling, or undefined output states. TI recommends connecting unused OE pins to V_CC to force associated outputs into high-impedance mode, and unused A inputs to GND or V_CC depending on desired default output state. This requirement applies to every instance of SN74ALVC16244ADGGR in the design.

Is the SN74ALVC16244ADGGR pin-compatible with older 74ALVC244 variants?

No, the SN74ALVC16244ADGGR is not pin-compatible with legacy 24-pin 74ALVC244 devices. It is a 48-pin TSSOP (DGG) part with four independent 4-bit sections, whereas the 74ALVC244 is an 8-bit device in SOIC-20 or TSSOP-20 packages. Direct replacement would require PCB redesign. However, the SN74ALVC16244ADGGR can replace four discrete 74ALVC244 units in space-constrained designs where 16-bit buffering is required.

Does the SN74ALVC16244ADGGR support hot-plug or live-insertion?

The SN74ALVC16244ADGGR supports hot-plug operation when OE is held high (Hi-Z) during insertion, preventing bus contention. Its I_OK rating (–50 mA clamp current) and 2000-V HBM ESD protection provide robustness against transient surges during live connection. However, TI does not guarantee hot-plug compliance without external series resistors or TVS diodes on data lines - system-level validation is required before deploying SN74ALVC16244ADGGR in hot-swap backplanes.
