Product details

Overview

SN74ALVCH162244DL 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 supports four independent 4-bit buffers (or two 8-bit or one 16-bit configuration), features bus-hold on all data inputs, and integrates 26-Ω series output resistors to suppress overshoot/undershoot - used in memory address buffering, clock distribution, and high-density bus interfacing.

For engineers reviewing the SN74ALVCH162244DL datasheet, SN74ALVCH162244DL pinout, SN74ALVCH162244DL application, or SN74ALVCH162244DL equivalent, key selection criteria include its 48-pin SSOP (DL) package, -40°C to +85°C industrial temperature range, 12-mA output sink capability, bus-hold input retention, and 3-state enable logic with symmetrical active-low OE inputs.

Technical Context

This device belongs to TI's Widebus™ family and uses EPIC™ submicron CMOS process. Its architecture implements four independent 4-bit buffer sections, each with dedicated active-low output-enable (OE) control and true (non-inverting) output logic.

All 16 data inputs feature integrated bus-hold circuitry eliminating external pullup/pulldown resistors; outputs are designed to drive transmission lines directly due to built-in 26-Ω series termination, supporting clean signal integrity without external components.

Key Specifications

V_CC Range	1.65 V to 3.6 V - enables interoperability across mixed-voltage systems including 1.8-V, 2.5-V, and 3.3-V logic domains.
Output Drive	±12 mA - sufficient to drive standard CMOS loads and moderate PCB trace capacitance without external buffering.
Bus-Hold Current	±25 µA to ±75 µA (V_I-dependent) - actively retains valid logic state on unused/floating inputs, preventing metastability.
Propagation Delay	4.2 ns (typ, V_CC = 3.3 V) - supports high-speed address/data buffering in memory and peripheral interfaces.
3-State Enable Time	5.6 ns (typ, V_CC = 3.3 V) - ensures fast output activation/deactivation for time-critical bus arbitration.
ESD Rating	>2000 V HBM - meets MIL-STD-883 Class 3015 requirements for robust handling in manufacturing and field environments.
Operating Temperature	-40°C to +85°C - qualified for industrial-grade embedded and computing applications.

Pinout & Package

SN74ALVCH162244DL is housed in a 48-pin Shrink Small-Outline Package (SSOP), DL variant, with 0.5-mm lead pitch and 12.6 mm × 6.2 mm body dimensions. The package is RoHS-compliant, moisture-sensitivity level 1, and rated for peak reflow at 260°C.

Pin/Terminal	Circuit Role	Design Meaning

V_CC (Pins 7, 21, 34, 48)	Power supply	Four distributed V_CC pins minimize IR drop and improve noise immunity across wide bus structures.
GND (Pins 4, 10, 15, 27, 32, 39)	Ground reference	Six GND pins provide low-inductance return paths and support simultaneous switching noise (SSN) suppression.

Key Features

Feature	Design Value
Integrated 26-Ω output series resistors	Eliminates need for external termination resistors, reducing BOM count and PCB area in high-speed bus designs.
Bus-hold on all 16 inputs	Maintains stable logic levels on unconnected or unterminated inputs - prevents false triggering in hot-swap or partial-population scenarios.

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
SN74LVC162244ADL	Lower drive strength (±24 mA vs ±12 mA), identical V_CC range and bus-hold, same DL package.	Better suited for higher-current loads but lacks integrated 26-Ω output resistors - requires external termination.	Select when higher output current is needed and board space allows discrete termination resistors.
74ALVCH162244DGGR	TSSOP-48 (DGG) package instead of SSOP-48 (DL); identical electrical specs, pinout, and thermal rating.	Smaller footprint (11.89 mm × 4.4 mm vs 12.6 mm × 6.2 mm) and different tape-and-reel packaging (2000/reel vs 1000/reel).	Select for space-constrained layouts or automated assembly requiring TSSOP-compatible feeders.

Compared with SN74LVC162244ADL, the SN74ALVCH162244DL trades higher current capability for built-in signal integrity features; compared with 74ALVCH162244DGGR, it offers identical functionality in a mechanically distinct SSOP package optimized for thermal dissipation and hand-soldering accessibility.

FAQ

What is the recommended power-up sequence for SN74ALVCH162244DL?

TI recommends tying all OE inputs to V_CC through a pullup resistor (minimum value determined by driver sink capability) to ensure outputs remain in high-impedance state during power ramp-up. This prevents bus contention before system initialization completes. The SN74ALVCH162244DL itself has no internal power sequencing requirement beyond monotonic V_CC rise.

Does SN74ALVCH162244DL support mixed-voltage operation between inputs and outputs?

No - the SN74ALVCH162244DL is a single-supply device operating from one V_CC rail (1.65 V to 3.6 V). Input voltage levels are referenced to this same V_CC, and outputs swing between GND and V_CC. It does not support level translation; for mixed-voltage interfaces, external translators or dual-supply buffers are required.

How does the bus-hold feature behave on SN74ALVCH162244DL during power-down?

Bus-hold remains functional as long as V_CC is above ~0.8 V. Below that threshold, the circuit loses bias and inputs float. For guaranteed state retention during full power loss, external hold circuitry or system-level supervision is advised. The SN74ALVCH162244DL datasheet specifies bus-hold current only within recommended V_CC range.

Can SN74ALVCH162244DL be used as a level shifter between 1.8-V and 3.3-V domains?

No - SN74ALVCH162244DL is not a level shifter. Its inputs are CMOS-compatible with V_CC-referenced thresholds (e.g., V_IL = 0.35×V_CC), and outputs swing rail-to-rail. To interface 1.8-V logic to a 3.3-V bus, a dedicated level-shifting device such as SN74AVC16T245 must be used alongside the SN74ALVCH162244DL.

What is the maximum capacitive load SN74ALVCH162244DL can drive reliably?

TI characterizes switching performance up to 50 pF load capacitance (see Figure 3 test conditions). With its 26-Ω series output resistance, the SN74ALVCH162244DL maintains signal integrity on PCB traces up to ~10 cm in length under typical FR-4 dielectric conditions. For heavier loads (>70 pF), derating of speed or addition of external termination may be necessary.
