Product details

Overview

74ALVC16244DL,112 from Nexperia is a 16-bit CMOS buffer/line driver with 3-state outputs, designed for bidirectional data bus interfacing in 2.5 V and 3.3 V systems. It features four independent output-enable inputs (1OE–4OE), each controlling four outputs, supports partial power-down via IOFF circuitry, and delivers ±24 mA drive at 3.0 V. It is used in memory address/data buffering and backplane interface applications requiring low-noise, high-speed signal routing.

For engineers reviewing the 74ALVC16244DL,112 datasheet, 74ALVC16244DL,112 pinout, 74ALVC16244DL,112 application, or 74ALVC16244DL,112 equivalent, key selection criteria include 3-state timing (tpd ≤ 3.0 ns at 3.3 V), overvoltage-tolerant inputs (5.5 V), IOFF-enabled power-down safety, and TSSOP48 package compatibility with high-density PCB layouts.

Technical Context

This device implements a quad 4-bit non-inverting buffer architecture with independent active-low output enables per group. Each of the four 4-bit sections operates synchronously with its own OE signal, enabling flexible bus segmentation without propagation delay stacking across groups.

IOFF circuitry disables all outputs when VCC = 0 V, blocking backflow current during partial power-down - critical for hot-swap and mixed-voltage system interoperability. Input overvoltage tolerance to 5.5 V allows direct interfacing with 5 V TTL logic while powered from 2.5 V or 3.3 V rails.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage range	1.2 V to 3.6 V - supports single-rail operation across legacy 2.5 V and modern 3.3 V logic domains
Propagation delay (tpd)	1.0 ns (min) to 3.0 ns (max) at VCC = 3.3 V - ensures sub-ns timing margin for 100+ MHz bus operation
Output drive strength	±24 mA at VCC = 3.0 V - sufficient to drive 50 Ω transmission lines directly without external termination
Input overvoltage tolerance	5.5 V on data inputs - enables safe interfacing with 5 V TTL signals without level shifters
IOFF current	Prevents backflow current during power-down - eliminates risk of latch-up or damage in mixed-power systems
Static power consumption	0.2 μA typical ICC per input pin - reduces quiescent current in battery-backed or low-power standby modes
ESD protection	HBM > 2000 V, MM > 200 V - meets industrial-grade robustness requirements for board-level handling

Pinout & Package

TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm lead pitch, surface-mount compatible with standard reflow profiles.

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE, 3OE, 4OE (pins 1, 48, 25, 24)	Active-low output enable	Each controls four corresponding Y outputs; HIGH forces high-impedance state for bus isolation
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	Non-inverting inputs grouped into four 4-bit channels; accept 1.2–5.5 V logic levels
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)	Data outputs	3-state buffered outputs with ±24 mA drive; support hot-swap and bus contention avoidance
VCC (pins 7,18,31,42)	Power supply	Four distributed VCC pins minimize supply inductance and reduce ground bounce in high-speed switching
GND (pins 4,10,15,21,28,34,39,45)	Ground reference	Eight GND pins provide low-impedance return paths, critical for noise suppression in 16-bit parallel interfaces

Key Features

Feature	Design Value
MultiByte flow-through pinout	Input/output pairs aligned across package edges - simplifies PCB trace routing and minimizes crosstalk in parallel buses
Low-inductance power distribution	Four VCC and eight GND pins - reduces simultaneous switching noise (SSN) and improves signal integrity at >100 MHz
Overvoltage-tolerant inputs	5.5 V max on data inputs - eliminates need for external level translators when interfacing with 5 V legacy peripherals
IOFF partial power-down	Outputs disabled and isolated when VCC = 0 V - prevents backfeed current in modular or hot-pluggable subsystems
Latch-up immunity	>100 mA per JESD78 Class II Level B - ensures reliability under transient overvoltage or ESD stress conditions

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
SN74ALVCH16244DGGR	Includes bus-hold circuitry on all inputs; otherwise identical pinout, timing, and drive specs	Eliminates external pull-up/down resistors on floating inputs - preferred for systems with undriven control lines	Select when input stability on unconnected or intermittently driven lines is required without added passives
74LVC16244APAG	Same function but in TSSOP48; lacks IOFF and 5.5 V overvoltage tolerance; max VCC = 3.6 V only	Lower cost alternative where partial power-down and 5 V interfacing are not needed	Choose for cost-sensitive consumer applications with fixed 3.3 V supply and no hot-swap requirements

Compared with SN74ALVCH16244DGGR, the 74ALVC16244DL,112 offers superior input overvoltage tolerance and IOFF protection but requires external bus-hold resistors if inputs float. Versus 74LVC16244APAG, it adds critical industrial features - IOFF and 5.5 V tolerance - at minimal cost premium.

FAQ

Does 74ALVC16244DL,112 support 1.8 V operation?

Yes. The device is fully specified from 1.2 V to 3.6 V, including 1.8 V. At 1.8 V, propagation delay is 2.8 ns (typical), input thresholds are VIH ≥ 1.2 V and VIL ≤ 0.6 V, and output drive is ±12 mA - verified per Table 6 and Table 7 of the official Nexperia datasheet Rev. 6.

Can 74ALVC16244DL,112 be used with 5 V inputs while powered at 3.3 V?

Yes. Its data inputs tolerate up to 5.5 V regardless of VCC level, enabling direct connection to 5 V TTL outputs without level shifters. This is explicitly guaranteed in Table 4 (Limiting Values) and Table 5 (Recommended Operating Conditions) of the datasheet.

What is the purpose of the four separate OE pins?

The four independent OE pins (1OE–4OE) allow selective 3-state control of each 4-bit output group. This enables dynamic bus segmentation - e.g., isolating memory banks or peripheral clusters independently - reducing contention and improving system-level timing predictability.

How does IOFF protect the device during partial power-down?

When VCC drops to 0 V, the IOFF circuit automatically disables all outputs, presenting high-impedance and blocking reverse current flow from live buses into the unpowered IC. This prevents latch-up and damage, as confirmed by functional description Section 1 and limiting values Table 4 in the Nexperia datasheet.
