Product details
Overview
74LVC16245APVG8 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 two busses in mixed-voltage systems. It features ±24mA drive strength, industrial temperature range (–40°C to +85°C), and supports hot insertion.
For engineers reviewing the 74LVC16245APVG8 datasheet, 74LVC16245APVG8 pinout, 74LVC16245APVG8 application, or 74LVC16245APVG8 equivalent, key selection criteria include 5V-tolerant I/O compatibility, dual 8-bit/16-bit configuration flexibility, output skew <1 ns, 3.3V supply operation with 2.7–3.6V extended range, and SSOP-48 package suitability for space-constrained PCB layouts.
Technical Context
The 74LVC16245APVG8 implements two independent 8-bit transceiver sections (A↔B), each controlled by dedicated DIR and OE pins, enabling configurable unidirectional or bidirectional flow per section. Its hysteresis-equipped inputs improve noise immunity in noisy industrial environments.
It operates as a level translator between 3.3V and 5V logic domains without external biasing, leveraging 5V-tolerant I/Os and rail-to-rail input thresholds (VIH = 2.0V min at VCC ≥ 2.7V). The ±24mA drivers maintain signal integrity under moderate capacitive loads while delivering tPLH/tPHL ≤ 4 ns at VCC = 3.3V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7V to 3.6V - supports wide-input supply tolerance for stable operation across voltage drift or ripple. |
| IO Drive Strength | ±24mA - enables direct driving of moderate fan-out loads (e.g., multiple LVC inputs or short traces) without buffers. |
| Output Skew (tSK(o)) | <1 ns - ensures tight timing alignment across all 16 outputs, critical for parallel bus integrity and setup/hold margin. |
| I/O Voltage Tolerance | 0V to 6.5V - allows safe interfacing with 5V peripherals while powered from 3.3V, eliminating level-shifter ICs. |
| Propagation Delay | 1 ns to 4 ns - guarantees sub-5 ns timing for high-speed 16-bit data transfers in real-time control or comms interfaces. |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade reliability in factory automation, telecom infrastructure, and embedded controllers. |
| Input Hysteresis | 100 mV - suppresses false triggering on slow or noisy signals, improving robustness in electrically harsh environments. |
Pinout & Package
74LVC16245APVG8 is housed in a 48-pin Shrink Small Outline Package (SSOP), green RoHS-compliant, with 0.5 mm pitch and exposed pad not present. Pin layout supports dual 8-bit sections (1A/1B and 2A/2B), each with independent direction (DIR) and output enable (OE) controls.
| 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. |
| 1OE, 2OE | Output Enable Input (Active LOW) | Disables both A and B ports of respective section into high-impedance state when HIGH. |
| 1A1–1A8, 2A1–2A8 | Side A I/O Port | Bidirectional data lines for first and second 8-bit bus; 5V tolerant, hysteresis-enabled. |
| 1B1–1B8, 2B1–2B8 | Side B I/O Port | Bidirectional data lines for complementary bus; identical electrical specs to Side A. |
| VCC (Pins 4, 19, 36, 47) | Power Supply | Four distributed VCC pins reduce supply inductance and improve noise rejection across wide bus. |
| GND (Pins 3, 18, 35, 48) | Ground Reference | Four GND pins provide low-impedance return paths, minimizing ground bounce during simultaneous switching. |
Key Features
| Feature | Design Value |
|---|---|
| 5V-tolerant I/O | Enables seamless integration into mixed 3.3V/5V systems without external level shifters or clamping diodes. |
| Hot-insertion support | Prevents bus contention and latch-up during live board insertion via power-up/down sequencing robustness. |
| ±24mA output drive | Drives up to 10 LVC loads or 15 pF trace capacitance at full speed, reducing need for external drivers. |
| Hysteresis on all inputs | Provides 100 mV noise margin, allowing reliable operation with slow-rise signals or EMI-prone industrial wiring. |
| Low static power | Typical ICC = 0.4 μW - minimizes quiescent current draw in always-on subsystems like backplane controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16245ADGGR | Same function and pinout; TI version in 48-pin TSSOP (0.5 mm pitch), slightly higher max tPHL (4.7 ns vs 4.0 ns). | Identical use cases but requires verification of TSSOP thermal performance in high-density layouts. | Select if TSSOP footprint preferred and thermal derating margins exist. |
| 74ALVC16245PW,118 | NXP variant in TSSOP-48; identical DC specs but lower max output drive (±24mA same), higher CPD (42 pF vs 38 pF). | Suitable for lower-frequency (<25 MHz) bus applications where dynamic power is less constrained. | Choose when sourcing diversity is required and 38 pF vs 42 pF CPD does not impact system power budget. |
Compared with SN74LVC16245ADGGR and 74ALVC16245PW,118, the 74LVC16245APVG8 offers the lowest propagation delay (1–4 ns) and tightest output skew (<1 ns), making it optimal for timing-critical 16-bit parallel interfaces where signal alignment and minimal latency are essential.

FAQ
What is the maximum operating frequency supported by the 74LVC16245APVG8?
The 74LVC16245APVG8 does not specify a maximum clock frequency because it is an asynchronous transceiver. Its usable data rate depends on system-level timing margins. With typical propagation delays of 1–4 ns and output skew <1 ns at VCC = 3.3V, it reliably supports parallel bus data rates up to ~100 MHz in well-designed layouts with controlled trace lengths and proper termination.
Does the 74LVC16245APVG8 require external pull-up or pull-down resistors on DIR or OE pins?
No, the 74LVC16245APVG8 does not require external biasing on DIR or OE pins. Its inputs feature built-in hysteresis and standard CMOS thresholds (VIH = 2.0V min, VIL = 0.8V max at VCC = 3.3V), allowing direct connection to 3.3V or 5V logic outputs. Pull resistors are only needed if driving from open-drain sources or floating control lines.
Can the 74LVC16245APVG8 be used to translate between 1.8V and 3.3V logic domains?
No, the 74LVC16245APVG8 is not rated for 1.8V operation. Its VCC range is strictly 2.7V to 3.6V, and its inputs are 5V-tolerant-not 1.8V-compatible. For 1.8V ↔ 3.3V translation, a dedicated dual-supply level shifter such as the TXB0108 or SN74AVCH16T245 is required instead of the 74LVC16245APVG8.
Is the 74LVC16245APVG8 pin-compatible with older 74LVC245 variants?
Yes, the 74LVC16245APVG8 is functionally and pin-compatible with other 48-pin SSOP/TSSOP 16-bit transceivers in the LVC family (e.g., 74LVC16245A), sharing identical pinout, electrical behavior, and logic functionality. However, always verify mechanical fit and thermal characteristics when substituting across package types (e.g., SSOP vs TSSOP).
What is the meaning of "PVG" in the part number 74LVC16245APVG8?
"PVG" in 74LVC16245APVG8 denotes the package type: Shrink Small Outline Package (SSOP), green (RoHS-compliant), supplied in tape-and-reel format ("8"). This matches the ordering code defined in the IDT/Renesas datasheet, confirming it is a 48-pin SSOP device with lead-free finish and moisture sensitivity level (MSL) appropriate for standard SMT assembly.
