Product details

Overview

74LVCH162245ADGG:5 from Nexperia is a 16-bit non-inverting transceiver with dual-direction control (nDIR), dual output enable (nOE), bus-hold on all data inputs, integrated 30 Ω series termination resistors, and 5 V tolerant I/O. It operates from 1.2 V to 3.6 V supply and supports −40 °C to +125 °C ambient range. It enables bidirectional level translation between 3.3 V and 5 V buses in high-speed memory or peripheral interconnects.

For engineers reviewing the 74LVCH162245ADGG:5 datasheet, 74LVCH162245ADGG:5 pinout, 74LVCH162245ADGG:5 application, or 74LVCH162245ADGG:5 equivalent, key selection criteria include bus-hold functionality, 30 Ω on-die termination, 5 V tolerance with sub-3.6 V V_CC, dual 8-bit cascading capability, and TSSOP48 package compatibility with JEDEC JESD8-7A/5A/C compliance.

Technical Context

This device implements two independent 8-bit transceiver blocks (A↔B), each with separate direction (nDIR) and output-enable (nOE) controls. Direction logic determines signal flow: when nDIR = LOW, A→B; when HIGH, B→A. Output states are fully 3-state controllable via active-low nOE, enabling bus isolation during disable.

All 16 data I/O pins feature bus-hold circuitry that maintains valid logic levels on floating inputs without external pull-ups. Both HIGH and LOW output stages integrate 30 Ω series resistors to suppress transmission-line reflections and reduce switching noise-critical for clean signal integrity in dense PCB layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	1.2 V to 3.6 V - Enables direct interface with 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters.
I/O voltage tolerance	Up to 5.5 V - Allows safe connection to 5 V buses while powered from ≤3.6 V, supporting mixed-voltage system translation.
Propagation delay	1.0 ns (min) to 5.7 ns (max) at V_CC = 3.0–3.6 V - Supports >100 MHz data rates in point-to-point or stubbed bus topologies.
Bus-hold current	±10 µA to ±75 µA (V_CC-dependent) - Actively sustains input logic state without external components, reducing BOM count and layout area.
Termination resistance	30 Ω series per I/O - Matches typical PCB trace impedance to minimize ringing and overshoot in short-run interconnects.
Operating temperature	−40 °C to +125 °C - Qualified for industrial and extended-temperature embedded control, motor drive, and power management applications.
ESD protection	HBM >2000 V, CDM >1000 V - Robust handling during board assembly and field operation without additional protection circuitry.

Pinout & Package

TSSOP48 package (SOT362-1): plastic thin shrink small outline, 48 leads, body width 6.1 mm, 0.5 mm pitch, lead coplanarity ≤0.1 mm, moisture sensitivity level 1 (MSL1).

Pin/Terminal	Circuit Role	Design Meaning
1DIR, 24DIR	Direction control input	Active-HIGH selects B→A data flow; LOW selects A→B - enables independent control of two 8-bit channels.
48nOE, 25nOE	Output enable input	Active-LOW disables outputs to high-impedance - allows cascading multiple devices on shared buses without contention.
1A[0:7], 2A[0:7]	Data I/O port A	8-bit bidirectional port with bus-hold and 30 Ω series termination - connects to controller-side bus (e.g., MCU parallel interface).
1B[0:7], 2B[0:7]	Data I/O port B	8-bit bidirectional port with bus-hold and 30 Ω series termination - connects to peripheral-side bus (e.g., SRAM, FPGA configuration interface).
7,18,31,42 V_CC	Power supply	Four distributed V_CC pins minimize IR drop and improve noise immunity across wide die area.
4,10,15,21,28,34,39,45 GND	Ground	Eight GND pins provide low-inductance return paths - critical for stable operation and reduced ground bounce in high-speed switching.

Key Features

Feature	Design Value
Integrated 30 Ω series termination	Eliminates need for discrete 33 Ω resistors on each line, saving 32 passives and PCB real estate in 16-bit interfaces.
Bus-hold on all data inputs	Maintains defined logic state on unused or unterminated I/O pins - removes requirement for 16 external pull-up/pull-down resistors.
5 V tolerant I/O at V_CC ≤3.6 V	Enables direct connection to legacy 5 V peripherals (e.g., older SRAM, CPLD) without external translators or voltage dividers.
Dual independent 8-bit control	Separate nDIR/nOE per 8-bit bank allows asymmetric bus configurations - e.g., one channel A→B only, other B→A only.
JEDEC-compliant voltage ranges	Fully compliant with JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) - ensures interoperability across industry-standard logic families.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC162245DGGR	No bus-hold; identical 30 Ω termination, 5 V tolerance, and TSSOP48 package.	Requires external pull-up/down resistors on unused inputs; less suitable for hot-plug or intermittent bus scenarios.	Select when cost sensitivity outweighs bus-hold convenience and board space permits discrete resistors.
74ALVC162245PAG	Higher speed (t_pd ≤3.8 ns at 3.3 V), but no bus-hold and narrower V_CC range (2.3–3.6 V).	Not usable below 2.3 V; unsuitable for 1.8 V or battery-backed systems requiring ultra-low V_CC.	Select only for maximum-speed deterministic timing where 1.2–2.3 V operation is unnecessary.

Compared with SN74LVC162245DGGR and 74ALVC162245PAG, the 74LVCH162245ADGG:5 uniquely combines bus-hold, wide 1.2–3.6 V operation, and 5 V tolerance - making it optimal for flexible, robust, and component-count-sensitive designs across industrial and automotive domains.

FAQ

What is the function of the bus-hold circuit in the 74LVCH162245ADGG:5?

The bus-hold circuit in the 74LVCH162245ADGG:5 actively maintains the last-valid logic state on each data input (1A[0:7], 2A[0:7], 1B[0:7], 2B[0:7]) when the input is floating or disconnected. It draws ±10 µA to ±75 µA (depending on V_CC) to hold VI below V_IL or above V_IH, eliminating the need for external pull-up or pull-down resistors and improving system reliability during hot-swap or partial initialization.

Can the 74LVCH162245ADGG:5 operate with a 1.8 V supply and interface to 5 V signals?

Yes, the 74LVCH162245ADGG:5 supports V_CC as low as 1.2 V and tolerates input voltages up to 5.5 V regardless of supply level. When powered at 1.8 V, it safely accepts 5 V logic signals on all I/O pins and drives compatible 1.8 V or 3.3 V loads - enabling seamless level translation without external circuitry in mixed-voltage systems.

How does the 30 Ω series termination in the 74LVCH162245ADGG:5 improve signal integrity?

The 30 Ω series termination resistors integrated into both HIGH and LOW output stages of the 74LVCH162245ADGG:5 match typical PCB trace impedances (40–70 Ω) in source-series configuration. This dampens reflections, reduces overshoot/ringing, and stabilizes edge transitions - particularly beneficial for stub-based or short-run interconnects up to 15 cm, without requiring discrete resistors or layout tuning.

What is the purpose of having two separate DIR and OE pins in the 74LVCH162245ADGG:5?

The dual DIR (1DIR, 2DIR) and dual OE (1OE, 2OE) pins in the 74LVCH162245ADGG:5 allow independent control of two 8-bit transceiver sections. This enables asymmetric configurations - such as one section operating A→B while the other runs B→A, or one section enabled while the other is isolated - simplifying cascaded bus architectures and reducing external logic complexity in multi-peripheral systems.

Is the 74LVCH162245ADGG:5 suitable for automotive applications?

The 74LVCH162245ADGG:5 is qualified for operation from −40 °C to +125 °C and features robust ESD protection (HBM >2000 V), making it suitable for non-safety-critical automotive applications like infotainment, body control, and telematics modules. However, it is not AEC-Q100 qualified; for safety-critical functions (e.g., ADAS, powertrain), consult Nexperia's automotive-grade alternatives.
