Product details
Overview
74LVCH162374APAG8 from Renesas Electronics is a 3.3V CMOS 16-bit edge-triggered D-type flip-flop with 3-state outputs, 5V-tolerant I/O, bus-hold, and industrial temperature range (–40°C to +85°C). It supports dual 8-bit or unified 16-bit register operation via independent OE/CLK controls, delivers ±12mA drive strength, and features <500ps output skew for high-speed data synchronization in mixed-voltage systems.
For engineers reviewing the 74LVCH162374APAG8 datasheet, 74LVCH162374APAG8 pinout, 74LVCH162374APAG8 application, or 74LVCH162374APAG8 equivalent, key selection criteria include 5V-tolerant I/O compatibility, bus-hold input retention, TSSOP-48 package footprint, low-skew timing performance, and industrial-grade reliability for data buffering in telecom and industrial control interfaces.
Technical Context
This device implements two independent 8-bit edge-triggered D-type registers sharing a common clock architecture, with separate active-low 3-state output enables per bank. Its bus-hold circuitry eliminates external pull resistors by retaining last valid input state during high-impedance conditions.
Designed using advanced dual-metal CMOS, it operates across VCC = 2.7V–3.6V with static power consumption of 0.4μW typical and supports 5V logic inputs while sourcing/sinking ±12mA at defined thresholds-enabling seamless interfacing between 3.3V and 5V domains without level shifters.
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 |
| tPLH / tPHL | 2ns min / 6.2ns max at VCC = 3.3V - guarantees sub-7ns propagation delay for high-throughput data latching |
| tSK(o) | ≤500ps - minimizes inter-output timing mismatch critical for parallel bus integrity |
| I/O Voltage Tolerance | 0V to 6.5V - allows direct connection to 5V logic without external protection or translation |
| Bus-Hold Current | ±75μA at VCC = 3V - actively sustains input state during floating conditions, removing need for external biasing |
| Output Drive | ±12mA - provides sufficient current to drive light loads and reduce line noise without external series termination |
| Operating Temperature | –40°C to +85°C - qualified for deployment in uncontrolled industrial enclosures and outdoor telecom infrastructure |
Pinout & Package
TSSOP-48 package with 0.5mm pitch, 12.5mm × 6.1mm body size, and exposed pad for thermal management. Pin numbering follows JEDEC MO-153 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1Q1–1Q8, 2Q1–2Q8 | 3-State Outputs | Individually controlled by respective OE; high-impedance when OE = HIGH, latched on CLK rising edge |
| 1D1–1D8, 2D1–2D8 | Data Inputs | Bus-hold enabled; retain last valid logic state when driven high-Z, eliminating pull-up/down resistors |
| 1CLK, 2CLK | Clock Inputs | Rising-edge sensitive; synchronizes data capture for corresponding 8-bit bank |
| 1OE, 2OE | Active-Low Output Enables | Independent control per 8-bit bank; enables/disables all eight outputs simultaneously |
| VCC, GND (×4) | Power & Ground | Distributed supply/return pins minimize switching noise and improve signal integrity across 16-bit bus |
Key Features
| Feature | Design Value |
|---|---|
| 5V-Tolerant I/O | Supports direct interface with legacy 5V logic in mixed-supply systems without level-shifting components |
| Integrated Bus-Hold | Eliminates external pull resistors on data/control lines, reducing BOM count and PCB area |
| Low-Noise Output Drivers | Series resistors embedded in output structure suppress ringing and EMI on lightly loaded traces |
| Flow-Through Pinout | Input-to-output signal routing simplifies PCB layout and minimizes trace length mismatch across parallel paths |
| Industrial Temp Rating | Validated operation from –40°C to +85°C ensures reliability in harsh factory and infrastructure environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit edge-triggered D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16374ADGGR | No bus-hold; requires external pull resistors on unused inputs; identical TSSOP-48 package and 3.3V operation | Lacks input state retention - unsuitable for systems with intermittent signal sources or hot-plug interfaces | Select when cost sensitivity outweighs need for bus-hold and system-level noise immunity is managed externally |
| 74ALVC16374PW,118 | Higher ICCZ (100μA vs. 10μA); no bus-hold; operates down to 1.65V VCC; same pinout | Better low-voltage compatibility but higher quiescent current; not rated for industrial temperature range | Prefer for battery-powered or ultra-low-voltage designs where extended VCC range is prioritized over thermal robustness |
Compared with SN74LVC16374ADGGR and 74ALVC16374PW,118, the 74LVCH162374APAG8 uniquely combines industrial temperature qualification, integrated bus-hold, and 5V-tolerant I/O in a single TSSOP-48 package-making it optimal for mission-critical mixed-voltage buffering where layout simplicity and reliability are non-negotiable.

FAQ
What is the maximum operating voltage for 74LVCH162374APAG8?
The 74LVCH162374APAG8 supports VCC from 2.7V to 3.6V, with absolute maximum terminal voltage rated at –0.5V to +6.5V relative to GND. Its 5V-tolerant I/O allows inputs up to 5.5V regardless of VCC, enabling safe interfacing with 5V logic while powered from 3.3V. This specification is verified across the full industrial temperature range (–40°C to +85°C).
Does 74LVCH162374APAG8 require external pull-up or pull-down resistors?
No, the 74LVCH162374APAG8 integrates bus-hold circuitry on all data and control inputs (1D1–1D8, 2D1–2D8, 1OE, 2OE, 1CLK, 2CLK), which actively retains the last valid logic state when inputs float. This eliminates the need for external pull resistors, reducing BOM cost and PCB space-confirmed in the Bus-Hold Characteristics table of the official Renesas datasheet.
What is the output skew specification for 74LVCH162374APAG8?
The 74LVCH162374APAG8 specifies a maximum output skew (tSK(o)) of 500ps across any two outputs switching in the same direction under VCC = 3.3V ± 0.3V and TA = –40°C to +85°C. This value is measured per the test methodology shown in the "Test Circuits and Waveforms" section and ensures tight timing alignment critical for parallel bus applications.
Can 74LVCH162374APAG8 be used in a 5V-only system?
Yes-the 74LVCH162374APAG8's I/O pins are 5V tolerant (up to 6.5V absolute max), and its inputs accept 5V logic levels even when VCC = 3.3V. However, VCC must remain within 2.7V–3.6V; it cannot be powered from 5V. This makes it ideal as a translator/buffer in 5V-to-3.3V domain crossings, as confirmed in the Applications and DC Electrical Characteristics sections.
What package type does 74LVCH162374APAG8 use?
The 74LVCH162374APAG8 uses a TSSOP-48 (Thin Shrink Small Outline Package) with green (RoHS-compliant) finish, 0.5mm lead pitch, and JEDEC MO-153 mechanical dimensions (12.5mm × 6.1mm body). This package is explicitly listed in the Ordering Information table and supported by Renesas' official documentation and distributor listings.
