Product details

Overview

74LCX162244MTDX from ON Semiconductor is a low-voltage 16-bit non-inverting buffer/line driver with nibble-level 3-STATE control, integrated 26 Ω output series resistors, 5V-tolerant I/O, and rated for 2.3–3.6 V_CC. It delivers 5.3 ns max propagation delay at 3.0 V and supports ±12 mA output drive. It is used in memory address buffering, clock distribution, and bus transceiver applications requiring noise-suppressed signaling.

For engineers reviewing the 74LCX162244MTDX datasheet, pinout, applications, or equivalent options, key selection criteria include its 48-pin TSSOP package, per-nibble OE control (OE1–OE4), 26 Ω built-in series termination, 5V input tolerance, and guaranteed AC timing across 2.3–3.6 V operation.

Technical Context

The 74LCX162244MTDX implements sixteen independent non-inverting buffers grouped into four 4-bit nibbles, each with dedicated active-low Output Enable (OE1–OE4) inputs. Its outputs integrate 26 Ω nominal series resistors to suppress transmission-line overshoot/undershoot without external components.

It operates within 2.3–3.6 V_CC, maintains 5V-tolerant inputs and outputs, and achieves 5.3 ns max t_PHL/t_PLH at V_CC = 3.0 V with C_L = 50 pF. The device features power-down high-impedance inputs/outputs and meets >500 mA latch-up immunity per JEDEC JESD78.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.3 V to 3.6 V - Enables direct interface with 2.5 V and 3.3 V logic systems while maintaining robust noise margins.
Propagation Delay (t_PD)	5.3 ns max at V_CC = 3.0 V, C_L = 50 pF - Ensures tight timing alignment in high-speed address/data buses.
Output Drive	±12 mA at V_CC = 3.0 V - Sufficient to drive terminated lines or multiple CMOS loads without external buffers.
Input/Output Voltage Tolerance	0 V to 5.5 V - Allows safe interfacing with legacy 5 V systems without level shifters.
Output Series Resistance	26 Ω nominal - Integrated on-die termination eliminates need for discrete series resistors and reduces EMI.
Quiescent ICC	20 µA max - Supports ultra-low static power in battery-backed or standby-sensitive designs.
Operating Temperature	−40 °C to +85 °C - Qualified for industrial-grade embedded and computing applications.

Pinout & Package

74LCX162244MTDX is packaged in a 48-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153 compliant, 6.1 mm wide, with 0.5 mm lead pitch. Pin assignments are identical to the SSOP variant (74LCX162244MEA) per datasheet Figure 1.

Pin/Terminal	Circuit Role	Design Meaning
OEn (OE1–OE4)	Active-low output enable per nibble	Four independent controls allow selective 4-bit gating - enables partial bus isolation without full 16-bit disable.
I0–I15	Buffer inputs	16 single-ended CMOS-compatible inputs; 5V tolerant, high-impedance when powered down.
O0–O15	Non-inverting buffered outputs	Each includes 26 Ω series resistor; drives up to ±12 mA; enters high-Z when corresponding OEn = HIGH.
V_CC	Power supply	Single 2.3–3.6 V supply; decoupling required at each V_CC pin pair per layout guidelines.
GND	Ground reference	Multiple GND pins (pins 12, 24, 36, 48) reduce ground bounce and improve signal integrity.

Key Features

Feature	Design Value
Integrated 26 Ω output series resistors	Eliminates need for 16 external termination resistors - reduces BOM count, PCB area, and layout complexity.
5V-tolerant I/O	Enables mixed-voltage system integration (e.g., 3.3 V core driving 5 V peripheral bus) without level translators.
Nibble-selectable 3-STATE control	Four OE inputs (OE1–OE4) support granular bus partitioning - critical for multi-master or segmented memory architectures.
Low-noise switching architecture	Patented EMI/noise reduction circuitry lowers dynamic ground bounce and crosstalk in dense routing environments.
High latch-up immunity	Exceeds 500 mA per JEDEC JESD78 - ensures robustness in noisy industrial or hot-plug scenarios.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit buffer/line driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74ALVC162244PW,118	Lower V_CC range (1.65–3.6 V); no integrated series resistors; 3.9 ns t_PD at 3.3 V.	Requires external 22–33 Ω series resistors for EMI control; better suited for ultra-high-speed, short-trace routing.	Select when minimal propagation delay is prioritized over board space savings and EMI suppression.
SN74LVC162244ADGGR	Same 1.65–3.6 V range; no built-in termination; higher I_OL/I_OH (24 mA); 4.2 ns t_PD at 3.3 V.	Lacks integrated 26 Ω resistors; requires more careful layout for signal integrity; supports heavier capacitive loads.	Choose for higher drive strength needs where external termination is acceptable and layout allows tighter impedance control.

Compared with 74ALVC162244PW,118 and SN74LVC162244ADGGR, the 74LCX162244MTDX trades marginal speed for integrated termination and proven noise suppression - reducing design risk in cost-sensitive, medium-speed industrial bus applications.

FAQ

What is the package type and lead count for 74LCX162244MTDX?

The 74LCX162244MTDX is supplied in a 48-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153 compliant, with 6.1 mm body width and 0.5 mm lead pitch. This package is distinct from the FBGA and SSOP variants and is optimized for automated surface-mount assembly in space-constrained industrial PCBs.

Does 74LCX162244MTDX require external series termination resistors?

No. The 74LCX162244MTDX integrates 26 Ω nominal series resistors on all 16 outputs, eliminating the need for discrete termination. This feature directly reduces PCB component count, layout complexity, and signal integrity risks associated with unterminated transmission lines.

Can 74LCX162244MTDX safely interface with 5 V logic inputs and outputs?

Yes. The 74LCX162244MTDX features 5V-tolerant inputs and outputs, meaning it accepts input voltages up to 5.5 V and drives outputs compatible with 5 V logic thresholds - enabling seamless connection to legacy 5 V peripherals without level-shifting circuitry.

How is 3-STATE control implemented on 74LCX162244MTDX?

The 74LCX162244MTDX provides four independent active-low Output Enable inputs (OE1–OE4), each controlling a 4-bit nibble (O0–O3, O4–O7, O8–O11, O12–O15). When an OE pin is LOW, its corresponding outputs drive; when HIGH, they enter high-impedance state - supporting flexible bus arbitration schemes.

What is the maximum propagation delay specification for 74LCX162244MTDX at 3.0 V?

The maximum propagation delay (t_PHL and t_PLH) for 74LCX162244MTDX is 5.3 ns at V_CC = 3.0 V, C_L = 50 pF, and T_A = −40 °C to +85 °C. This value is guaranteed across process, voltage, and temperature corners per the Fairchild DS500471 datasheet.
