Product details
Overview
74LVC16827APAG8 from Renesas Electronics (formerly IDT) is a 3.3V CMOS 20-bit non-inverting buffer with 5V-tolerant I/O, ±24mA drive strength, and industrial temperature range (–40°C to +85°C), used for bus interface buffering in mixed-voltage data/address paths and backplane driving.
For engineers reviewing the 74LVC16827APAG8 datasheet, 74LVC16827APAG8 pinout, 74LVC16827APAG8 application, or 74LVC16827APAG8 equivalent, key selection factors include 5V I/O tolerance, dual-output-enable control flexibility, output skew <500ps, tPLH/tPHL ≤4.1ns at 3.3V, and TSSOP-56 package compatibility with high-capacitance load driving.
Technical Context
The 74LVC16827APAG8 implements two independent 10-bit buffer banks or one unified 20-bit buffer via paired active-low output enables (1OE1/1OE2 and 2OE1/2OE2), supporting flow-through pin organization for PCB layout simplification. All inputs feature hysteresis (100mV typ.) to enhance noise immunity in noisy environments.
It operates across VCC = 2.7V–3.6V, delivers ±24mA output drive per pin, and maintains full 5V tolerance on all I/O pins-enabling seamless level translation between 3.3V logic and legacy 5V systems without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7V to 3.6V - supports extended supply margin and brown-out resilience in industrial power rails |
| I/O Voltage Tolerance | 0V to 6.5V - allows direct interfacing with 5V peripherals without level shifters |
| Output Drive | ±24mA - sufficient to drive heavy capacitive loads (e.g., >50pF backplanes) while maintaining signal integrity |
| Propagation Delay | tPLH/tPHL ≤4.1ns @3.3V - enables reliable operation in high-speed address/data buses up to ~200MHz |
| Output Skew | tSK(o) ≤500ps - ensures tight timing alignment across all 20 outputs for synchronous bus applications |
| Input Hysteresis | 100mV typ. - improves noise rejection on slow-rising or electrically noisy control signals |
| Quiescent ICC | ≤10μA - ultra-low static power ideal for always-on industrial monitoring interfaces |
Pinout & Package
74LVC16827APAG8 is housed in a 56-pin Thin Shrink Small Outline Package (TSSOP), 12.5mm × 6.1mm body, 0.5mm pitch, lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A1–1A10, 2A1–2A10 | Data Inputs | 20 dedicated input pins accepting 3.3V or 5V logic; hysteresis enhances noise margin |
| 1Y1–1Y10, 2Y1–2Y10 | 3-State Outputs | 20 buffered, ±24mA capable outputs; high-impedance state enabled by OE pairs |
| 1OE1/1OE2, 2OE1/2OE2 | Active-Low Output Enables | Four independent enable controls allow granular bank-level output gating (10-bit or 20-bit mode) |
| VCC (Pins 11, 28, 42, 55) | Power Supply | Four distributed VCC pins reduce IR drop and improve high-frequency decoupling |
| GND (Pins 10, 15, 29, 47) | Ground Reference | Four GND pins minimize ground bounce and support clean signal return paths |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 20-bit buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16244ADGGR | 16-bit (not 20-bit); identical 3.3V VCC, 5V-tolerant I/O, ±24mA drive, TSSOP-48 | Lacks 4 I/O channels; requires two devices for 20-bit coverage; higher board area and routing complexity | Select when 16-bit granularity suffices and pin count must be minimized |
| 74ALVC16827PW,118 | Same 20-bit function, 3.3V VCC, 5V-tolerant I/O, but SOIC-56 package (larger footprint, 1.27mm pitch) | SOIC-56 incompatible with fine-pitch TSSOP layouts; lower thermal performance; no hot-insertion support | Select only for legacy SOIC-based designs where re-layout is impractical |
Compared with SN74LVC16244ADGGR and 74ALVC16827PW,118, the 74LVC16827APAG8 uniquely delivers native 20-bit width in compact TSSOP-56 with verified hot-insertion capability and tighter output skew-making it optimal for space-constrained, high-reliability industrial backplane and telecom applications.

FAQ
What is the operating temperature range for the 74LVC16827APAG8?
The 74LVC16827APAG8 is rated for industrial temperature operation from –40°C to +85°C. This range is validated across all electrical specifications including propagation delay, output drive, and 5V I/O tolerance. The device uses advanced CMOS process technology to ensure stable parametric performance across this full range, making it suitable for deployment in uncontrolled industrial enclosures and outdoor telecom cabinets where ambient temperatures fluctuate widely.
Does the 74LVC16827APAG8 support hot insertion?
Yes, the 74LVC16827APAG8 explicitly supports hot insertion as confirmed in its official datasheet features list. Its 5V-tolerant I/O structure, controlled power-up sequencing behavior, and robust ESD protection (>2000V per MIL-STD-883) enable safe insertion and removal while the system remains powered. This capability is critical for modular telecom and industrial systems requiring field-replaceable line cards without system downtime.
How many output enable controls does the 74LVC16827APAG8 have, and how are they organized?
The 74LVC16827APAG8 has four output enable inputs: 1OE1, 1OE2, 2OE1, and 2OE2-organized as two independent NAND-ed pairs. When both enables in a pair are low, the corresponding 10-bit bank (1Y1–1Y10 or 2Y1–2Y10) is active; otherwise, outputs go high-impedance. This architecture allows flexible configuration as either two separate 10-bit buffers or one unified 20-bit buffer, enhancing design adaptability in segmented bus systems.
What is the maximum capacitive load the 74LVC16827APAG8 can drive while maintaining timing specs?
The 74LVC16827APAG8 is characterized to maintain its published switching specifications-including tPLH/tPHL ≤4.1ns and tSK(o) ≤500ps-at CL = 50pF, as defined in the official test conditions. Its ±24mA drive strength enables reliable operation into typical backplane loads (e.g., 30–60pF). For heavier loads (>60pF), propagation delay increases predictably per the device's output impedance profile, but functionality remains intact up to the absolute max IOUT rating of ±50mA.
Is the 74LVC16827APAG8 pin-compatible with earlier IDT versions like the 74LVC16827A?
Yes, the 74LVC16827APAG8 is a tape-and-reel packaged variant of the original IDT74LVC16827A and retains identical pinout, electrical characteristics, and functional behavior. The "PAG8" suffix denotes TSSOP-56 packaging with green (lead-free) finish and tape-and-reel delivery-no changes to silicon, pin assignment, or timing. Designers may substitute 74LVC16827APAG8 directly into existing footprints qualified for the base 74LVC16827A part.
