Product details
Overview
74ALVCH162245DGG:5 from Nexperia is a 16-bit non-inverting 3-State bus transceiver with integrated 30Ω series termination resistors, dual direction control (1DIR/2DIR), dual output enable (1OE/2OE), and bus hold on all data I/Os. It operates from 1.2V to 3.6V, delivers 2.4ns typical propagation delay at 2.5V/30pF, and supports bidirectional data flow in computing and industrial backplane interfaces.
For engineers reviewing the 74ALVCH162245DGG:5 datasheet, 74ALVCH162245DGG:5 pinout, 74ALVCH162245DGG:5 application, or 74ALVCH162245DGG:5 equivalent, key selection criteria include its 30Ω on-die termination, bus hold functionality eliminating external resistors, dual 8-bit cascading capability, and TSSOP48 package compatibility with high-density PCB layouts.
Technical Context
The 74ALVCH162245DGG:5 implements two independent 8-bit transceiver sections (A↔B), each with dedicated nDIR and nOE controls, enabling flexible bidirectional bus isolation and direction management. Its CMOS design ensures low dynamic power dissipation (CPD = 27pF enabled, 4pF disabled) and TTL-level compatibility across supply voltages.
Bus hold circuitry actively maintains valid logic states on floating inputs without external biasing, while integrated 30Ω series resistors suppress signal reflections on transmission lines-critical for clean edge integrity in 50pF-loaded 3.3V systems operating up to 200MHz effective data rates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2V to 3.6V - Enables direct interface with 1.8V, 2.5V, and 3.3V logic domains without level shifters. |
| Propagation Delay (tPHL/tPLH) | 2.4ns typical at VCC = 2.5V, CL = 30pF - Supports >200MHz data throughput in point-to-point links. |
| Integrated Termination | 30Ω series resistor per output - Reduces external component count and PCB footprint for impedance-matched signaling. |
| Bus Hold Current | ±45µA to ±175µA (VCC = 2.3V–3.0V) - Actively clamps unused inputs to valid logic levels, preventing metastability. |
| 3-State Enable/Disable Time | tPZH/tPHZ = 3.0ns / 2.6ns typical at VCC = 3.3V - Ensures fast bus arbitration and minimal contention window during direction switching. |
| Input Capacitance (CI) | 4.0pF - Minimizes loading on driving sources, preserving signal rise/fall times in high-speed buses. |
| Quiescent Supply Current | 0.2µA to 40µA - Ultra-low static power enables use in battery-backed or always-on subsystems. |
Pinout & Package
74ALVCH162245DGG:5 is housed in a 48-pin Plastic Thin Shrink Small Outline Package (TSSOP48), body width 6.1 mm, compliant with JEDEC MO-153, pin pitch 0.5 mm. The package features multiple VCC and GND pins distributed across the perimeter to minimize ground bounce and power supply inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 24 | 1DIR / 2DIR | Active-HIGH direction control inputs - Set data flow direction per 8-bit section (A→B or B→A). |
| 48, 25 | 1OE / 2OE | Active-LOW output enable - Independently place each 8-bit port into high-impedance state for bus sharing. |
| 2–9, 11–12, 13–20, 22–23, 26–29, 30, 32–33, 35–36, 37–40, 41, 43–44, 46–47 | 1A0–1A7, 1B0–1B7, 2A0–2A7, 2B0–2B7 | Bidirectional data I/Os with bus hold - Support true 16-bit or split 8-bit transceiver operation; no external pull resistors required. |
| 4, 10, 15, 21, 28, 34, 39, 45 | GND | Eight dedicated ground terminals - Reduce common-impedance coupling and improve noise immunity. |
| 7, 18, 31, 42 | VCC | Four dedicated supply pins - Lower power delivery impedance and stabilize local VCC under switching transients. |
Key Features
| Feature | Design Value |
|---|---|
| 30Ω On-die Series Termination | Eliminates need for 16 discrete 30Ω SMT resistors, saving >10mm² PCB area and reducing BOM count. |
| Bus Hold Circuitry | Maintains stable logic states on unconnected or unterminated data lines, preventing false triggering in hot-swap or partial-load scenarios. |
| MULTIBYTE™ Flow-through Pinout | Minimizes trace crossovers and routing congestion in dense backplane or memory interface layouts. |
| Dual Independent Control | Separate nDIR/nOE per 8-bit bank enables asymmetric bus configurations (e.g., 8-bit upstream + 8-bit downstream). |
| JEDEC 8-1A Compliance | Guarantees interoperability with industry-standard 3.3V LVTTL and mixed-voltage system designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVCH162245DGGR | TSSOP48 package, identical pinout and electrical specs; TI part with same 30Ω termination and bus hold. | No functional deviation - validated for drop-in replacement in existing TI-design reference layouts. | Select when sourcing from TI-authorized channels or requiring TI-specific qualification documentation. |
| 74LVC162245ADGG | No integrated 30Ω termination; lower drive strength (24mA vs 32mA); same bus hold and voltage range. | Requires external 30Ω series resistors per line for signal integrity - increases BOM cost and layout complexity. | Choose only if termination is handled externally or if lower power consumption (CPD = 19pF) outweighs integration benefit. |
Compared with SN74ALVCH162245DGGR, the 74ALVCH162245DGG:5 offers identical functionality and pin compatibility but differs in manufacturer qualification and long-term supply chain governance; versus 74LVC162245ADGG, it provides superior signal integrity out-of-box at the cost of slightly higher quiescent current.

FAQ
What is the maximum recommended operating temperature for the 74ALVCH162245DGG:5?
The 74ALVCH162245DGG:5 is rated for continuous operation from –40°C to +85°C ambient temperature. This range is validated per the device's Recommended Operating Conditions table and applies to both SSOP and TSSOP packages. Operation beyond +85°C requires derating of power dissipation and is not supported for long-term reliability.
Does the 74ALVCH162245DGG:5 require external pull-up or pull-down resistors on its data lines?
No, the 74ALVCH162245DGG:5 includes active bus hold circuitry on all data I/O pins (1A0–1A7, 1B0–1B7, 2A0–2A7, 2B0–2B7), which maintains valid logic states on floating inputs without external resistors. This feature eliminates the need for pull-ups or pull-downs in unconnected or partially loaded bus configurations.
Can the 74ALVCH162245DGG:5 be used as two independent 8-bit transceivers?
Yes, the 74ALVCH162245DGG:5 supports dual 8-bit operation via separate direction (1DIR/2DIR) and output enable (1OE/2OE) controls. Each half (1A/1B and 2A/2B) functions independently, allowing asymmetric data flow control-for example, one side transmitting while the other receives-or complete isolation of either 8-bit segment.
What is the purpose of the integrated 30Ω termination resistor in the 74ALVCH162245DGG:5?
The integrated 30Ω series termination resistor in the 74ALVCH162245DGG:5 is placed directly at each output driver to match typical PCB trace impedances (e.g., 50–75Ω) in source-series terminated configurations. This minimizes signal reflections, reduces ringing, and improves signal integrity-especially critical in high-speed parallel buses with 50pF loads at 3.3V.
Is the 74ALVCH162245DGG:5 pin-compatible with older 74ALVC162245 variants?
No, the 74ALVCH162245DGG:5 is not pin-compatible with standard 74ALVC162245 devices due to differences in internal termination architecture and bus hold implementation. While both use TSSOP48 packaging, the 74ALVCH162245DGG:5 has distinct DC and AC characteristics-including tighter VIH/VIL thresholds and added 30Ω resistors-that require verification against original layout constraints before substitution.
