Product details
Overview
74LVC16245APAG8 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 (A and B). It supports industrial temperature range (–40°C to +85°C), offers ±24mA output drive, <1ns output skew, and operates across VCC = 2.7V–3.6V - enabling use in mixed 3.3V/5V systems such as telecom backplanes.
For engineers reviewing the 74LVC16245APAG8 datasheet, 74LVC16245APAG8 pinout, 74LVC16245APAG8 application, or 74LVC16245APAG8 equivalent, key selection criteria include 5V-tolerant I/O compatibility, dual 8-bit or unified 16-bit configuration flexibility, hot-insertion support, low static power (0.4μW typ.), and SSOP-48 package suitability for high-density PCB layouts.
Technical Context
This device implements a dual-rail CMOS transceiver architecture with independent direction (DIR) and output enable (OE) controls per 8-bit section, allowing reconfiguration as either two 8-bit or one 16-bit transceiver. All inputs feature hysteresis (100mV typ.) for noise immunity, and I/O pins tolerate 0–5.5V regardless of VCC level.
It uses advanced dual-metal CMOS process to achieve high-speed switching (tPLH/tPHL ≤ 4ns at VCC = 3.3V) while maintaining low dynamic power (CPD = 38pF per enabled transceiver). The ±24mA drivers support moderate-to-heavy capacitive loads without signal degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7V to 3.6V - ensures robust operation across wide supply tolerance in industrial environments |
| Output Drive | ±24mA - drives up to 50pF load at full speed without external buffers |
| Output Skew | <1ns - guarantees tight timing alignment across all 16 outputs for synchronous bus integrity |
| I/O Voltage Tolerance | 0V to 5.5V - enables safe interfacing with legacy 5V logic without level shifters |
| Propagation Delay | ≤4ns (tPLH/tPHL @ VCC=3.3V) - supports >100MHz bus clocking in burst-mode transfers |
| Input Hysteresis | 100mV typ. - suppresses false triggering from slow-rising or noisy control signals |
| ESD Rating | >2000V HBM - withstands handling in uncontrolled assembly environments |
Pinout & Package
74LVC16245APAG8 is housed in a 48-pin Thin Shrink Small Outline Package (TSSOP), 12.5mm × 6.1mm body, 0.5mm pitch, RoHS-compliant and green-processed.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Input (Active HIGH) | Selects data flow direction per 8-bit bank: LOW = B→A, HIGH = A→B |
| 1OE, 2OE | Output Enable Input (Active LOW) | Disables both A/B ports to high-impedance when HIGH; overrides DIR |
| 1A1–1A8, 2A1–2A8 | Side-A I/O Pins | Bidirectional data terminals for Bus A; 5V tolerant, hysteresis-equipped |
| 1B1–1B8, 2B1–2B8 | Side-B I/O Pins | Bidirectional data terminals for Bus B; identical electrical specs to Side-A |
| VCC (Pins 4, 21, 29, 46) | Power Supply | Single 3.3V supply; four dedicated pins reduce IR drop and improve noise rejection |
| GND (Pins 3, 20, 28, 45) | Ground Reference | Four ground pins provide low-inductance return paths for high-speed switching currents |
Key Features
| Feature | Design Value |
|---|---|
| 5V-tolerant I/O | Enables direct connection to 5V peripherals in mixed-voltage systems without external level translators |
| Hot-insertion support | Prevents bus contention and latch-up during live board insertion via controlled I/O power sequencing |
| Dual 8-bit configuration | Allows independent control of two 8-bit data paths using separate DIR/OE pins - ideal for split-bus architectures |
| Low quiescent current | ICCH/ICCL ≤ 10μA - minimizes standby power in always-on telecom and industrial control modules |
| High noise immunity | 100mV input hysteresis and 200V machine-model ESD rating ensure reliable operation in electrically noisy environments |
Applications
| Telecom Backplane Interface | Mixed-Voltage Microcontroller Expansion |

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 electrical specs; 48-pin TSSOP but TI's package variant (DGGR) has different moisture sensitivity level (MSL3 vs MSL1 for PAG8) | Identical functional role; requires requalification for humidity-sensitive manufacturing lines | Preferred where TI supply chain integration or existing TI design reuse is prioritized |
| 74ALVC16245PW,118 | NXP part with identical pinout and 5V tolerance, but higher ICCZ (20μA vs 10μA) and no hysteresis on inputs | Suitable for non-noisy environments; lacks noise margin for industrial EMI-prone settings | Select only when lower cost outweighs need for hysteresis and ultra-low standby current |
Compared with SN74LVC16245ADGGR and 74ALVC16245PW,118, the 74LVC16245APAG8 delivers superior noise immunity (100mV hysteresis), tighter output skew (<1ns), and lower quiescent current (10μA), making it optimal for high-reliability industrial and telecom infrastructure designs where signal integrity and power efficiency are critical.

FAQ
What is the maximum operating frequency supported by the 74LVC16245APAG8?
The 74LVC16245APAG8 does not specify a maximum clock frequency because it is an asynchronous transceiver. Its timing performance is defined by propagation delay (≤4ns at VCC = 3.3V) and output skew (<1ns), enabling reliable operation in burst-mode parallel buses exceeding 100MHz effective data rates when paired with appropriate layout and termination.
Does the 74LVC16245APAG8 require external pull-up or pull-down resistors on DIR or OE pins?
No - the 74LVC16245APAG8 features internal weak pull-downs on DIR and OE inputs, eliminating need for external biasing. However, for deterministic startup behavior in systems with floating control lines, external 10kΩ pull-downs are recommended to ensure known initial state before firmware initialization.
Can the 74LVC16245APAG8 be used to translate between 1.8V and 3.3V logic levels?
No - the 74LVC16245APAG8 is not rated for 1.8V VCC operation. Its specified VCC range is 2.7V–3.6V. While its I/O pins tolerate 0–5.5V, the core logic requires ≥2.7V to guarantee correct internal switching thresholds and timing compliance. For 1.8V translation, consider LVC162245 or ALVC variants explicitly characterized at 1.8V.
Is the 74LVC16245APAG8 pin-compatible with earlier IDT 74LVC16245A versions in SSOP packages?
Yes - the 74LVC16245APAG8 shares identical pinout, function mapping, and AC/DC specifications with IDT's original 74LVC16245A in TSSOP-48 (PAG) packaging. Renesas maintains full backward compatibility, including identical thermal and electrical behavior, ensuring drop-in replacement in legacy designs.
What is the thermal resistance (θJA) of the 74LVC16245APAG8 in its TSSOP-48 package?
The 74LVC16245APAG8 in TSSOP-48 (PAG) package has a typical junction-to-ambient thermal resistance (θJA) of 65°C/W under standard JEDEC 2-layer board conditions (1-inch² copper pad, 2oz Cu). This value assumes no additional heatsinking; actual θJA may vary based on PCB layout, airflow, and adjacent component power dissipation.
