Product details
Overview
74LVC162245APAG8 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 asynchronous data transfer 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 industrial temperature operation (–40°C to +85°C).
For engineers reviewing the 74LVC162245APAG8 datasheet, 74LVC162245APAG8 pinout, 74LVC162245APAG8 application, or 74LVC162245APAG8 equivalent, this device supports voltage translation between 3.3V and 5V domains, enables bus isolation via active-low OE control, and delivers low-noise A-port outputs via integrated series resistors - critical for signal integrity in high-speed digital interconnects.
Technical Context
The 74LVC162245APAG8 implements dual 8-bit transceiver functionality within a single 48-pin TSSOP package, supporting independent direction control (DIR) and output enable (OE) per section. Its dual-drive architecture provides asymmetric current capability: A-port outputs are optimized for low-noise operation with ±12mA drive strength and built-in series termination, while B-port outputs deliver higher ±24mA drive for heavier loads.
It operates across VCC = 2.7V to 3.6V, with full 5V tolerance on all I/O pins - enabling safe interfacing with legacy 5V logic without level shifters. The device guarantees tPLH/tPHL ≤ 4.8ns (typ.) and tSK(o) ≤ 500ps at VCC = 3.3V, meeting timing-critical requirements in data communication backplanes and telecom interface modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7V to 3.6V - supports wide supply margin in industrial power rails; 3.3V ±0.3V nominal ensures compatibility with standard LVC logic families. |
| Drive Strength (A port) | ±12mA - reduces ringing and overshoot on lightly loaded traces; integrated series resistors suppress line noise without external components. |
| Drive Strength (B port) | ±24mA - drives heavier capacitive loads (e.g., longer PCB traces or multiple inputs) while maintaining VOL ≤ 0.55V at 24mA. |
| I/O Voltage Tolerance | 0V to 6.5V - allows direct connection to 5V TTL/CMOS signals without clamping diodes or external protection. |
| Output Skew (tSK(o)) | ≤500ps - ensures tight timing alignment across all 16 outputs, critical for parallel bus integrity in synchronous data capture. |
| Propagation Delay (tPLH/tPHL) | 1.0–4.0ns (typ. at 3.3V) - enables reliable operation up to ~200MHz bus rates with sufficient setup/hold margin. |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments including base station control cards and factory automation controllers. |
Pinout & Package
74LVC162245APAG8 is packaged in a 48-pin Thin Shrink Small Outline Package (TSSOP), 0.5mm pitch, body width 6.1mm, RoHS-compliant and green (Pb-free). Pinout follows industry-standard dual transceiver layout with mirrored A/B I/O banks and dedicated DIR/OE controls per 8-bit section.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Input (Active HIGH) | Determines data flow direction per 8-bit section: HIGH = A→B, LOW = B→A; enables independent bidirectional control of two buses. |
| 1OE, 2OE | Output Enable Input (Active LOW) | Places corresponding 8-bit port in high-impedance state when HIGH; tie to VCC via pullup for power-up isolation. |
| 1A1–1A8, 2A1–2A8 | Side A I/O Pins | 3.3V CMOS-compatible inputs/outputs with ±12mA drive and integrated series resistance for EMI reduction. |
| 1B1–1B8, 2B1–2B8 | Side B I/O Pins | 5V-tolerant I/O with ±24mA drive strength; suitable for driving legacy 5V loads or fanout-heavy destinations. |
| VCC (Pins 4, 20, 36, 48) | Power Supply | Four distributed VCC pins minimize supply impedance and improve noise immunity across the 48-pin array. |
| GND (Pins 3, 19, 35, 47) | Ground Reference | Four dedicated GND pins provide low-inductance return paths, essential for stable switching performance at high speed. |
Key Features
| Feature | Design Value |
|---|---|
| Asymmetric Drive Architecture | A-port's ±12mA with internal series resistance reduces simultaneous switching noise; B-port's ±24mA handles high-capacitance interconnects without external buffers. |
| 5V-Tolerant I/O Across Full Range | All 32 I/O pins accept 0–5.5V input voltages regardless of VCC setting (2.7–3.6V), eliminating need for external level translators in mixed-supply systems. |
| Low-Noise Output Skew Control | tSK(o) ≤ 500ps ensures matched propagation delays across all outputs - critical for maintaining data eye integrity in parallel 16-bit interfaces. |
| Industrial Temperature Qualification | Guaranteed operation from –40°C to +85°C with full DC/AC specs met, supporting deployment in uncontrolled ambient environments like telecom cabinets and motor drives. |
| Ultra-Low Static Power | ICCL ≤ 10μA at VCC = 3.6V - enables use in always-on subsystems (e.g., system management controllers) without thermal penalty. |
Applications
| Telecom Backplane Interface | Industrial PLC I/O Module |

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 | Same function and pinout; TI version in 48-pin TSSOP; slightly higher ICCZ (15μA vs. 10μA) and wider VOH min. spec at 24mA load. | Valid for TI-centric BOMs; identical thermal profile but requires validation of OE pullup resistor value due to differing IIH spec. | Select when sourcing from TI-authorized channels or when requiring TI's long-term product continuity program. |
| 74ALVC162245PW,118 | NXP variant in TSSOP; higher drive (±24mA on both ports); no A-port series resistors; tSK(o) = 600ps (max). | Better suited for symmetric high-drive needs; lacks A-port noise suppression - requires external termination for clean edges on light loads. | Choose when balanced high-current drive is prioritized over low-noise A-side signaling, e.g., in memory buffer applications. |
Compared with SN74LVC162245ADGGR and 74ALVC162245PW,118, the 74LVC162245APAG8 uniquely combines asymmetric drive optimization, integrated A-port termination, and lowest output skew - making it optimal for noise-sensitive, timing-critical 3.3V-to-5V bridging where signal integrity outweighs raw drive strength.

FAQ
What is the maximum operating frequency supported by the 74LVC162245APAG8?
The 74LVC162245APAG8 does not specify a maximum clock frequency, as it is an asynchronous transceiver. Its usable data rate depends on system-level timing margins. With typical propagation delays of 1.0–4.0ns and output skew ≤500ps at VCC = 3.3V, it reliably supports parallel bus data rates up to ~200MHz in well-designed layouts with controlled impedance and proper termination. Actual achievable frequency must be validated per application PCB stackup and load.
Can the 74LVC162245APAG8 be used for unidirectional data transfer only?
Yes, the 74LVC162245APAG8 supports unidirectional operation. By holding one DIR input constant (e.g., HIGH for A→B flow) and controlling OE to enable/disable the path, the device functions as a 16-bit unidirectional buffer. Its dual-section architecture also allows using one 8-bit section for A→B and the other for B→A simultaneously - enabling full-duplex point-to-point links without external logic.
Is the 74LVC162245APAG8 pin-compatible with older IDT 74LVC162245 variants?
Yes, the 74LVC162245APAG8 maintains identical pinout, electrical behavior, and timing specs with earlier IDT-branded 74LVC162245A devices in TSSOP packages (e.g., 74LVC162245APAG). It is a direct replacement following Renesas' acquisition of IDT, with no PCB or firmware changes required for drop-in substitution in existing designs.
How should OE be handled during power-up to prevent bus contention with the 74LVC162245APAG8?
To ensure high-impedance state at power-up, OE pins (1OE and 2OE) must be held HIGH until VCC stabilizes. This is achieved by connecting each OE to VCC through a pullup resistor. The minimum resistor value depends on the driver's sink capability; for the 74LVC162245APAG8, a 10kΩ pullup is typically sufficient given its IIH ≤ ±5μA. Avoid tying OE directly to GND or leaving it floating.
Does the 74LVC162245APAG8 require external series resistors on the A-port outputs?
No, external series resistors are not required on the A-port outputs of the 74LVC162245APAG8. The device integrates optimized series resistance internally to reduce line noise and overshoot when driving light loads - a key differentiator from standard LVC transceivers. This feature eliminates two external components per A-port line, saving board space and improving signal integrity without design overhead.
