Product details
Overview
CLVC1G126IDCKREP from Texas Instruments is a single 3-state noninverting bus buffer gate designed for 1.65-V to 5.5-V VCC operation, with ±24-mA output drive at 3.3 V, 3.7-ns max propagation delay (tpd) at 3.3 V, Ioff support for partial-power-down mode, and operation across −40°C to 85°C. It serves as a level-translating line driver in low-power digital interface circuits.
For engineers reviewing the CLVC1G126IDCKREP datasheet, CLVC1G126IDCKREP pinout, CLVC1G126IDCKREP application, or CLVC1G126IDCKREP equivalent, this page delivers verified functional identity, SC-70 (DCK) package mapping, confirmed 5-pin terminal roles, JEDEC-compliant latch-up and ESD ratings, and two validated alternative parts for industrial interface design.
Technical Context
This device implements a single-channel noninverting buffer with active-high output-enable control (OE), enabling high-impedance (Z) state when OE is low. Its logic diagram confirms direct A→Y signal path with no inversion, and OE directly gates output transistor stack without internal latching.
Designed for mixed-voltage system interfacing, it accepts input voltages up to 5.5 V independent of VCC, supports 1.65-V minimum supply, and features Ioff circuitry that disables outputs during power-down to prevent backflow current - critical for hot-swap and partial-power-down architectures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability between 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains |
| tpd (max) | 3.7 ns at VCC = 3.3 V, CL = 15 pF - ensures timing compliance in sub-10-ns digital control paths |
| IO Drive | ±24 mA at VCC = 3.3 V - drives standard LVTTL/LVCMOS loads without external buffering |
| Ioff | <±10 µA at VI/VO = 5.5 V - blocks damaging current flow during system power sequencing |
| ESD Rating | 2000-V HBM, 200-V MM, 1000-V CDM - meets industrial-grade robustness requirements per JESD22 |
| Latch-Up | >100 mA per JESD78 Class II - guarantees immunity to destructive parasitic SCR activation |
| ICC (max) | 10 µA - enables ultra-low static power in battery-backed or always-on monitoring nodes |
Pinout & Package
CLVC1G126IDCKREP is housed in a 5-pin SC-70 (DCK) package measuring 2.15 mm × 1.40 mm × 1.10 mm (max height), with gull-wing leads, RoHS-compliant NiPdAu finish, and MSL Level-1 rating (260°C reflow unlimited).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output-enable control input | Active-high signal; drives Y to high-impedance when low - requires pulldown resistor for power-up safety |
| 2 (A) | Data input | Noninverting input accepting 0–5.5 V; compatible with higher-voltage sources even at low VCC |
| 3 (GND) | Ground reference | Primary return path for all internal logic and output current; must be low-impedance for noise immunity |
| 4 (VCC) | Supply voltage | Power rail for internal logic and output stage; decoupling capacitor required within 1 cm |
| 5 (Y) | 3-state noninverting output | Drives load when OE = high; enters high-Z when OE = low - supports bus sharing and signal isolation |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65 V–5.5 V) | Eliminates need for level shifters in multi-rail systems such as MCU-to-peripheral interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single 3-state noninverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G126DBVR | Same logic function and SC-70 package, but commercial-grade (−40°C to 85°C) with standard qualification; no enhanced DMS or controlled baseline. | Lacks extended manufacturing pedigree and DMS support - suitable for non-critical commercial designs only. | Select SN74LVC1G126DBVR only if long-term supply continuity and military/aerospace traceability are not required. |
| SN74LVC1G126QDBVRQ1 | Automotive-qualified (AEC-Q100 Grade 2, −40°C to 105°C); identical pinout and electrical specs, but with additional stress testing and lot traceability. | Required for automotive ECUs; supports higher ambient temperature and stricter reliability validation than CLVC1G126IDCKREP. | Choose SN74LVC1G126QDBVRQ1 when deploying into passenger cabin or powertrain control systems requiring AEC-Q100 compliance. |
Compared with CLVC1G126IDCKREP, SN74LVC1G126DBVR offers cost savings without enhanced supply chain controls, while SN74LVC1G126QDBVRQ1 adds automotive qualification and extended temperature range - neither is pin-compatible drop-in replacements without verifying qualification scope and procurement terms.

FAQ
What is the primary function of the CLVC1G126IDCKREP?
The CLVC1G126IDCKREP is a single 3-state noninverting bus buffer gate. Its core function is to drive digital signals with level translation and output enable control - passing A to Y when OE is high, and placing Y in high-impedance when OE is low. This behavior makes CLVC1G126IDCKREP ideal for bus isolation, GPIO expansion, and mixed-voltage interface applications where signal directionality and power sequencing matter.
Does the CLVC1G126IDCKREP support operation below 1.8 V?
Yes, the CLVC1G126IDCKREP is fully specified down to 1.65 V VCC, with guaranteed performance including tpd, VOH/VOL, and IO drive at that minimum supply. At VCC = 1.65 V, it delivers ±4 mA output drive and maintains valid logic thresholds (VIH = 0.65×VCC, VIL = 0.35×VCC). This enables use in ultra-low-power systems such as energy-harvesting sensors where CLVC1G126IDCKREP operates reliably at near-threshold voltages.
How does the Ioff feature protect the CLVC1G126IDCKREP during power-down?
The Ioff circuitry in CLVC1G126IDCKREP actively disables both input and output structures when VCC = 0 V, limiting leakage current to <±10 µA even if input or output pins are biased to 5.5 V. This prevents reverse current flow that could damage upstream drivers or disrupt powered-down sections of a system - a critical safeguard in modular systems where CLVC1G126IDCKREP interfaces with live backplanes or hot-swappable cards.
What is the maximum capacitive load the CLVC1G126IDCKREP can drive while maintaining timing specs?
The CLVC1G126IDCKREP's published switching characteristics (e.g., 3.7-ns tpd) are measured with CL = 15 pF. At CL = 30 pF, tpd increases to 4.5 ns (VCC = 3.3 V); at CL = 50 pF, it reaches 4.5 ns max. While CLVC1G126IDCKREP can physically drive >50 pF loads, timing margins degrade beyond 30 pF - for reliable 100-MHz operation, keep total load ≤15 pF or add series termination to manage slew rate and ringing.
Is the CLVC1G126IDCKREP pin-compatible with standard SN74LVC1G126 variants?
Yes, CLVC1G126IDCKREP shares identical SC-70 (DCK) 5-pin layout, pin functions (OE/A/GND/VCC/Y), and footprint with SN74LVC1G126DBVR and SN74LVC1G126QDBVRQ1. However, CLVC1G126IDCKREP is not a generic drop-in replacement: its enhanced product qualifications (controlled baseline, DMS support, extended pedigree) require verification of sourcing documentation and procurement terms before substitution in existing designs.
