Product details
Overview
74LVC162245APFG from Renesas Electronics (formerly IDT) is a 3.3V CMOS 16-bit bus transceiver with 3-state outputs and 5V-tolerant I/O, designed for bidirectional data flow between A and B buses in mixed-voltage systems. It features ±12mA drive on the A port, ±24mA on the B port, <500ps output skew, and operates across –40°C to +85°C.
For engineers reviewing the 74LVC162245APFG datasheet, 74LVC162245APFG pinout, 74LVC162245APFG application, or 74LVC162245APFG equivalent, key selection criteria include 5V-tolerant I/O compatibility, dual-drive strength asymmetry (A vs. B port), industrial temperature support, and SSOP-48 package footprint constraints.
Technical Context
The 74LVC162245APFG implements two independent 8-bit transceiver sections, each with separate DIR and OE controls, enabling flexible 8-bit or 16-bit operation. Direction control (DIR) selects data flow direction (A→B or B→A), while active-low OE places outputs in high-impedance state for bus isolation.
It uses advanced dual-metal CMOS technology with integrated series resistors on the A-port outputs to reduce line noise under light loads. All I/O pins tolerate 5V inputs regardless of VCC (2.7V–3.6V), supporting seamless level translation in 3.3V/5V mixed-supply systems without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7V to 3.6V - supports both normal (3.3V ±0.3V) and extended supply operation |
| A-Port Drive | ±12mA - optimized for low-noise, light-load bus driving with built-in series resistance |
| B-Port Drive | ±24mA - higher-current capability for driving heavier capacitive loads or longer traces |
| Output Skew | <500ps - ensures tight timing alignment across all outputs within same bank |
| I/O Voltage Tolerance | 0V to 5.5V - enables direct interfacing with 5V logic without level shifters |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded and communications equipment |
| Static ICC | <10μA - ultra-low quiescent power ideal for power-sensitive applications |
Pinout & Package
74LVC162245APFG is housed in a 48-pin Shrink Small Outline Package (SSOP), green RoHS-compliant, with 0.635mm lead pitch and 12.8mm × 7.5mm body dimensions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Input (Active HIGH) | Selects data path: DIR = HIGH → A→B; DIR = LOW → B→A |
| 1OE, 2OE | Output Enable Input (Active LOW) | Drives all associated outputs into high-Z when HIGH; required pull-up to VCC for power-up safety |
| 1A1–1A8, 2A1–2A8 | Side-A I/O Pins | Bi-directional interface for first and second 8-bit bus segments; ±12mA drive, series-resistor damped |
| 1B1–1B8, 2B1–2B8 | Side-B I/O Pins | Bi-directional interface for complementary bus segments; ±24mA drive, no series damping |
| VCC (Pins 4, 21, 39, 46) | Power Supply | Four dedicated VCC pins minimize IR drop and improve noise immunity across wide SSOP body |
| GND (Pins 3, 20, 38, 45) | Ground Reference | Four GND pins provide low-inductance return paths for both A and B port switching currents |
Key Features
| Feature | Design Value |
|---|---|
| Asymmetric Output Drive Strength | A port (±12mA) and B port (±24mA) allow optimized signal integrity per bus segment-low-noise A-side for sensitive receivers, high-drive B-side for long traces |
| 5V-Tolerant I/O Architecture | All 32 I/O pins accept 0–5.5V inputs independent of VCC, eliminating external level translators in mixed-voltage backplanes and daughtercards |
| Industrial Temperature Qualification | Guaranteed operation from –40°C to +85°C enables use in base stations, industrial PLCs, and telecom line cards without derating |
| Low-Noise A-Port Output Structure | Integrated series resistors suppress ringing and EMI on lightly loaded stubs, reducing need for external termination in point-to-point or short-bus topologies |
| High-Speed Switching Performance | tPLH/tPHL ≤ 4.8ns (3.3V), tPZH/tPHZ ≤ 6.3ns - meets timing budgets for 100+ MHz parallel bus interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC162245ADGGR | TSSOP-48 package; identical electrical specs but 0.5mm pitch and 12.5mm × 6.1mm footprint | Preferred where board space is constrained and automated placement supports fine-pitch packages | Select when layout allows TSSOP-48 and thermal dissipation requirements match SSOP-48 |
| 74ALVC162245PAG | Higher speed (tPLH ≤ 3.4ns @ 3.3V); 2.5V–3.6V VCC range only; no 5V tolerance on I/O | Suitable for pure 3.3V systems requiring sub-4ns propagation delay, not mixed-voltage designs | Choose only if 5V tolerance is unnecessary and timing margin demands <3.5ns propagation |

FAQ
What is the maximum operating voltage on I/O pins of the 74LVC162245APFG?
The 74LVC162245APFG supports up to 5.5V on all I/O pins regardless of VCC level, enabling direct connection to 5V logic families without external level-shifting circuitry. This 5V tolerance is guaranteed across the full industrial temperature range (–40°C to +85°C) and applies to all 32 I/O terminals-A-port, B-port, and control inputs alike.
Does the 74LVC162245APFG require external pull-up resistors on OE pins?
Yes-the 74LVC162245APFG OE inputs are active-low and must be pulled up to VCC during power-up to ensure outputs remain in high-impedance state until firmware asserts control. The minimum pull-up resistor value depends on the driver's current-sinking capability; typical designs use 4.7kΩ to 10kΩ resistors tied to VCC.
Can the 74LVC162245APFG be used as two independent 8-bit transceivers?
Yes-the 74LVC162245APFG contains two fully independent 8-bit transceiver sections (1A/1B and 2A/2B), each with dedicated DIR and OE controls. This allows simultaneous bidirectional communication on two separate buses-for example, one section handling address/data multiplexing while the other manages control/status signals.
What is the difference between A-port and B-port drive strength in the 74LVC162245APFG?
The A-port delivers ±12mA output drive with integrated series resistance to suppress ringing on light loads, while the B-port provides higher ±24mA drive without internal damping-optimized for driving heavier capacitive loads or longer PCB traces. This asymmetry allows system designers to assign noise-sensitive or timing-critical signals to the A-port and high-fanout paths to the B-port.
Is the 74LVC162245APFG pin-compatible with older IDT 74LVC162245A variants?
Yes-the 74LVC162245APFG maintains identical pinout, electrical behavior, and timing characteristics as the original IDT 74LVC162245A in SSOP-48 packaging. It is a direct replacement with enhanced manufacturing compliance (RoHS, green molding compound) and updated quality documentation under Renesas ownership.
