Product details
Overview
74FCT162823CTPVG8 from Renesas Electronics is an 18-bit bus interface register with dual 9-bit or unified 18-bit operation, clock enable and asynchronous clear controls, ±24mA balanced output drive, and industrial temperature range (–40°C to +85°C). It serves as a low-noise, high-speed parity bus register in synchronous systems such as telecom backplanes and industrial control I/O modules.
For engineers reviewing the 74FCT162823CTPVG8 datasheet, 74FCT162823CTPVG8 pinout, 74FCT162823CTPVG8 application, or 74FCT162823CTPVG8 equivalent, key selection criteria include output skew (<0.5 ns), ground bounce (<0.6 V), 3-state output enable/disable timing, and compatibility with 5V TTL-level systems requiring noise-immune bus interfacing.
Technical Context
The 74FCT162823CTPVG8 implements two independent 9-bit register sections-each with dedicated clock (xCLK), clock enable (xCLKEN), clear (xCLR), and output enable (xOE) inputs-enabling flexible partitioned or full-width data latching. Its flow-through pinout minimizes PCB trace length asymmetry.
All inputs feature hysteresis (≥100 mV) for enhanced noise immunity, and outputs integrate current-limiting resistors to suppress ground bounce and undershoot without external termination. The device operates strictly at VCC = 5.0 V ±10% and is not 3.3V-compatible.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0 V ±10% - mandates dedicated 5V rail; incompatible with mixed-voltage 3.3V/5V systems without level translation |
| Output Drive | ±24 mA - sufficient to directly drive 50Ω transmission lines or multiple TTL loads without buffers |
| Output Skew | <0.5 ns - ensures deterministic timing across all 18 outputs for high-speed parallel bus capture |
| Ground Bounce | <0.6 V at VCC=5V, TA=25°C - reduces simultaneous switching noise in dense backplane layouts |
| tPLH / tPHL | 1.5–4.7 ns (CL=50pF) - supports >200 MHz register clock rates in clean signal environments |
| Input Hysteresis | ≥100 mV - rejects sub-10 ns noise spikes on clock or control lines in electrically noisy industrial settings |
| Operating Temp | –40°C to +85°C - qualified for deployment in uncontrolled industrial enclosures and outdoor telecom cabinets |
Pinout & Package
74FCT162823CTPVG8 is housed in a 56-pin TSSOP package (PVG suffix), 12.5 mm × 6.1 mm × 1.2 mm body, 0.5 mm pitch, RoHS-compliant and green molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 11, 21, 31, 41, 51 | 1CLR, 2CLR, 1CLKEN, 2CLKEN, 1OE, 2OE | Active-low asynchronous clear and control enables - require pull-up resistors for default inactive state |
| 2, 12, 22, 32, 42, 52 | 1CLK, 2CLK, 1D1–1D9, 2D1–2D9 | Synchronous clock and data inputs - routed with matched length to minimize skew between register banks |
| 3–10, 13–20, 23–30, 33–40, 43–50, 53–56 | 1Q1–1Q9, 2Q1–2Q9, GND, VCC | 3-state outputs and power pins - VCC/GND pairs distributed across package edges to reduce impedance and improve decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24mA Output Drivers | Eliminates need for external series termination resistors on 50Ω traces, reducing BOM count and layout area |
| Flow-Through Pinout | Input-to-output signal path alignment minimizes layer transitions and crosstalk in high-density routing |
| Hysteresis on All Inputs | 100 mV noise margin prevents false triggering from EFT or radiated interference in industrial environments |
| Low Output Skew (<0.5 ns) | Enables reliable capture of 18-bit parallel data at >200 MHz system clock rates without deskew logic |
| Industrial Temperature Range | Validated operation from –40°C to +85°C supports deployment in fanless enclosures and outdoor base stations |
Applications
| Telecom Backplane Interface | Industrial PLC I/O Module |
|---|---|

IC Role / Device Role / Timing Role: 18-bit latch acting as a synchronous interface between ADC output bus and FPGA-based memory controller with precise clock domain crossing. Use Value: Low ground bounce (<0.6 V) prevents corruption of adjacent analog measurement channels during high-frequency sampling bursts. | Use Scenario: Interfacing 18-bit precision ADC outputs to real-time DSP processors in vibration monitoring systems deployed in factory floors. IC Role / Device Role / Timing Role: Bus register with asynchronous clear for safe initialization and 3-state outputs for multiplexed bus sharing among multiple ADCs. Use Value: Industrial temperature rating and input hysteresis ensure stable operation amid thermal cycling and EMI from nearby motor drives and inverters. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 18-bit bus register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74FCT162823ATPVG8 | Same pinout and function; wider propagation delay max (10 ns vs. 4.7 ns) due to older speed grade | Acceptable where clock frequency ≤80 MHz; less suitable for >100 MHz synchronous capture | Select when cost sensitivity outweighs timing margin requirements and full-speed performance is not needed |
| SN74ABT16823DGGR | Different pinout (56-pin TSSOP but non-flow-through); no hysteresis; higher ICCZ (500 µA vs. 1.5 mA typical) | Requires PCB redesign; lacks noise immunity for harsh industrial use; higher static power in standby | Consider only if legacy ABT footprint compatibility is mandatory and noise environment is benign |
Compared with 74FCT162823CTPVG8, the AT-speed variant trades timing margin for cost, while the ABT16823 alternative sacrifices noise immunity and layout simplicity for legacy compatibility-neither offers drop-in replacement capability without verification.

FAQ
What is the operating voltage range for the 74FCT162823CTPVG8?
The 74FCT162823CTPVG8 operates exclusively at VCC = 5.0 V ±10% (4.5 V to 5.5 V). It is not specified or characterized for 3.3 V operation, and applying voltages outside this range may cause functional failure or permanent damage. All DC and AC parameters-including output drive, propagation delay, and noise margin-are guaranteed only within this 5V window.
Does the 74FCT162823CTPVG8 support hot-swap or live-insertion?
No, the 74FCT162823CTPVG8 does not support hot-swap. Its absolute maximum ratings specify no tolerance for VCC ramp sequencing or input voltage application prior to VCC stabilization. Applying signals to inputs before VCC reaches 4.5 V risks latch-up or excessive ICC due to undefined internal bias conditions. Proper power-rail sequencing is required in systems where board insertion occurs under power.
What is the meaning of "flow-through pinout" for the 74FCT162823CTPVG8?
The flow-through pinout of the 74FCT162823CTPVG8 arranges inputs and corresponding outputs on opposite sides of the TSSOP package (e.g., data inputs on left edge, matching outputs on right edge), enabling straight-line PCB routing with minimal layer changes. This reduces trace length mismatch, crosstalk, and stub effects-critical for maintaining signal integrity across all 18 bits in high-speed parallel buses.
Can the 74FCT162823CTPVG8 be used as a direct replacement for the 74FCT162823ATPVG8?
Yes, the 74FCT162823CTPVG8 is pin- and function-compatible with the 74FCT162823ATPVG8, differing only in AC timing specifications: the 'C' speed grade guarantees tighter propagation delay (max 4.7 ns vs. 10 ns) and faster enable/disable times. No PCB or firmware changes are required-only timing budget revalidation is needed when upgrading from AT to CT.
Is the 74FCT162823CTPVG8 compliant with JEDEC standards for 5V TTL interfacing?
Yes, the 74FCT162823CTPVG8 meets JEDEC Standard JESD8-6 for 5V TTL-compatible logic levels: VIH = 2.0 V min, VIL = 0.8 V max, VOH = 2.4 V min at –24 mA, and VOL = 0.55 V max at 24 mA. Its input thresholds and output drive align with legacy TTL and CMOS families, ensuring interoperability with 74LS, 74ALS, and other 5V logic without level shifters.
