Product details

Overview

SN74LVCH162244ADGG from Nexperia is a 16-bit non-inverting 3-state buffer/line driver with integrated 30 Ω series output termination resistors, bus-hold inputs, and 5 V tolerant I/O. It operates from 1.2 V to 3.6 V supply, supports −40 °C to +125 °C ambient, and enables mixed-voltage interfacing between 3.3 V and 5 V logic domains in high-noise digital backplanes and memory interfaces.

For engineers reviewing the SN74LVCH162244ADGG datasheet, SN74LVCH162244ADGG pinout, SN74LVCH162244ADGG application, or SN74LVCH162244ADGG equivalent, key selection criteria include its 30 Ω on-die series termination, bus-hold input retention (eliminating external pull-ups), 5 V tolerance on all I/O pins, and quad independent 3-state enable control for flexible data bus partitioning.

Technical Context

This device implements four independent 4-bit non-inverting buffers, each controlled by a dedicated active-low output enable (1OE–4OE). Each output stage integrates matched 30 Ω series resistors in both HIGH and LOW states to dampen transmission-line reflections and reduce switching noise on PCB traces.

The SN74LVCH162244ADGG includes bus-hold circuitry on all data inputs (A[0:3] groups), maintaining last-valid logic state when inputs float-critical for unused data lines in hot-swap or partial-bus-enable configurations. Control inputs (OE) lack bus-hold, per datasheet specification.

Key Specifications

Key Features

Feature	Design Value
5 V tolerant I/O	Supports direct interface with legacy 5 V TTL/CMOS logic while powered from 1.2–3.6 V supplies - eliminates level translators in mixed-voltage systems.
Integrated 30 Ω series termination	Reduces PCB component count and layout complexity for impedance-matched parallel buses - improves signal integrity without external resistors.
Bus-hold on all data inputs	Maintains valid logic state on floating inputs - prevents undefined behavior in partially populated or dynamically reconfigured data paths.
Quad independent 3-state control	Enables selective isolation of four 4-bit sub-buses - ideal for modular memory expansion, configurable peripheral interfaces, and fault-containment architectures.
Low-inductance multi-pin power/ground	Four VCC and eight GND pins minimize simultaneous switching noise (SSN) and ensure stable rail delivery during full 16-bit switching events.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit non-inverting buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC162244ADGG	No bus-hold circuitry on inputs; otherwise identical pinout, electrical specs, and package.	Requires external pull-up/pull-down resistors on unused inputs to prevent floating states.	Select when bus-hold is unnecessary and lowest possible static power is prioritized (IBHL/IBHH = 0).
74ALVC162244PW	Higher drive strength (±24 mA vs ±12 mA), faster tpd (1.8 ns typ at 3.3 V), but no integrated 30 Ω termination or bus-hold.	Suitable for shorter trace lengths with external termination; not drop-in for noise-sensitive or floating-input scenarios.	Select for maximum speed in compact PCB layouts where external termination and biasing are acceptable.

Compared with SN74LVC162244ADGG, the SN74LVCH162244ADGG adds bus-hold to eliminate external bias components, while compared with 74ALVC162244PW, it trades peak speed for built-in signal integrity features-making it optimal for robust, maintainable industrial and medical designs.

FAQ

What is the function of the bus-hold circuit in SN74LVCH162244ADGG?

The bus-hold circuit in SN74LVCH162244ADGG actively maintains the last-valid logic state on all 16 data inputs (A[0:3] groups) when those inputs are left floating. This eliminates the need for external pull-up or pull-down resistors, simplifying design and improving reliability in hot-swap or partial-bus-enable configurations. Control inputs (OE) do not have bus-hold.

Can SN74LVCH162244ADGG operate with a 1.2 V supply voltage?

Yes, SN74LVCH162244ADGG is fully specified to operate from 1.2 V to 3.6 V. At 1.2 V, it delivers functional performance with propagation delay up to 11.0 ns and supports −40 °C to +125 °C ambient operation. Input thresholds scale with VCC, and 5 V tolerance remains active regardless of supply voltage.

How does the 30 Ω series termination in SN74LVCH162244ADGG improve signal integrity?

The 30 Ω series termination resistors in SN74LVCH162244ADGG are integrated into both HIGH and LOW output stages to match typical PCB trace impedances (50–75 Ω). This damps reflections, reduces overshoot/ringing, and lowers EMI-enabling cleaner edges and reliable operation on longer traces without discrete resistors.

Is SN74LVCH162244ADGG pin-compatible with SN74LVC162244ADGG?

Yes, SN74LVCH162244ADGG is pin-compatible with SN74LVC162244ADGG in the same TSSOP48 package (SOT362-1). The only functional difference is the presence of bus-hold circuitry on all data inputs in the LVCH version; OE pin behavior, timing, and DC specs are otherwise identical.

What is the maximum output current rating for SN74LVCH162244ADGG?

SN74LVCH162244ADGG is rated for ±12 mA DC output current per pin under recommended operating conditions. Absolute maximum ratings allow ±50 mA short-duration current, but sustained operation above ±12 mA may exceed thermal limits or degrade timing performance. Output voltage specifications (VOH/VOL) are guaranteed at ±12 mA.
