Texas Instruments SN74LVC07AQPWRG4Q1

Overview

SN74LVC07AQPWRG4Q1 from Texas Instruments is an automotive-qualified hex buffer/driver with open-drain outputs, designed for 1.65 V to 5.5 V V_CC operation, supporting 24 mA sink current per output and input voltage tolerance up to 5.5 V. It enables level translation in mixed-voltage systems (e.g., 1.8-V/3.3-V-to-5-V interfaces) and wired-OR logic implementation in automotive body control modules.

For engineers reviewing the SN74LVC07AQPWRG4Q1 datasheet, SN74LVC07AQPWRG4Q1 pinout, SN74LVC07AQPWRG4Q1 application, or SN74LVC07AQPWRG4Q1 equivalent, key selection criteria include open-drain drive capability, AEC-Q100 qualification, wide V_CC range, latch-up immunity (>250 mA), and TSSOP-14 package compatibility with high-density PCB layouts.

Technical Context

This device implements six independent non-inverting buffers, each with an open-drain output stage that requires external pull-up for logic-high assertion. Its inputs accept voltages up to 5.5 V regardless of V_CC, enabling robust level-shifting across supply domains without additional circuitry.

The SN74LVC07AQPWRG4Q1 uses LVC logic family architecture with TTL-compatible thresholds at 3.3 V and CMOS-compatible thresholds at 5 V, and its propagation delay ranges from 1 ns (V_CC = 1.8 V) to 2.9 ns (V_CC = 3.3 V) under 30-pF load conditions - critical for timing-sensitive automotive signal conditioning.

FAQ

What is the maximum sink current per output of the SN74LVC07AQPWRG4Q1?

The SN74LVC07AQPWRG4Q1 supports a maximum sink current of 24 mA per open-drain output when V_CC = 3 V, as specified in the Recommended Operating Conditions table. This rating enables direct driving of LEDs, small relays, and I²C bus loads without external amplification. Derating applies at higher temperatures or lower V_CC; for example, at V_CC = 2.7 V, the rated sink current is 12 mA.

Is the SN74LVC07AQPWRG4Q1 compatible with 5-V input signals while operating at 1.8-V V_CC?

Yes, the SN74LVC07AQPWRG4Q1 accepts input voltages up to 5.5 V regardless of V_CC level - including when powered at 1.8 V. This feature is explicitly confirmed in the datasheet's "Inputs and Open-Drain Outputs Accept Voltages up to 5.5 V" bullet and Absolute Maximum Ratings table, enabling seamless level translation between 5-V legacy peripherals and low-voltage controllers.

Does the SN74LVC07AQPWRG4Q1 have built-in ESD protection?

The SN74LVC07AQPWRG4Q1 incorporates on-die ESD protection structures meeting JEDEC JS-001 Class 2 (≥2 kV HBM) and JESD22-A114 standards, as implied by its AEC-Q100 qualification and latch-up performance exceeding 250 mA per JESD 17. No external ESD diodes are required for typical automotive board-level protection when used within recommended operating conditions.

Can the SN74LVC07AQPWRG4Q1 be used as a logic-level translator for I²C buses?

Yes, the SN74LVC07AQPWRG4Q1 is commonly deployed for I²C level translation: two channels serve as open-drain repeaters for SDA and SCL, with pull-up resistors referenced to respective voltage domains (e.g., 1.8-V MCU side and 3.3-V sensor side). Its 1–2.9 ns propagation delay and 5.5-V-tolerant inputs ensure reliable 400-kHz I²C operation without direction-control logic.

What is the thermal resistance (θ_JA) of the SN74LVC07AQPWRG4Q1 in its TSSOP-14 package?

The SN74LVC07AQPWRG4Q1 in the PW (TSSOP-14) package has a junction-to-ambient thermal resistance (θ_JA) of 113°C/W, as specified in the Absolute Maximum Ratings table. This value assumes standard JEDEC 2-layer board conditions (1-inch² copper pad); actual thermal performance improves with enhanced PCB copper area or thermal vias beneath the exposed pad region.
