Texas Instruments SN74LV07APWRG4

Overview

SN74LV07APWRG4 from Texas Instruments is a hex buffer/driver IC with open-drain outputs, designed for 2-V to 5.5-V V_CC operation. It performs Y = A logic in positive logic, supports mixed-mode voltage translation (e.g., 3.3-V input to 5-V output), delivers up to 16 mA sink current at 5 V, and features I_off for partial power-down protection. It is used in bus interface, level-shifting, and wired-OR logic applications in telecom infrastructure and set-top boxes.

For engineers reviewing the SN74LV07APWRG4 datasheet, SN74LV07APWRG4 pinout, SN74LV07APWRG4 application, or SN74LV07APWRG4 equivalent, key selection criteria include open-drain drive capability, 5.5-V tolerant inputs/outputs, I_off support for hot-insertion, wide supply range (2–5.5 V), and TSSOP-14 package compatibility with high-density PCB layouts.

Technical Context

The SN74LV07APWRG4 implements six independent non-inverting buffers with open-drain outputs, enabling active-low wired-OR and active-high wired-AND configurations when multiple outputs share a pull-up resistor. Its I_off circuitry disables outputs during power-down, preventing back-current flow when V_CC = 0 V.

Input voltage tolerance extends to 5.5 V regardless of V_CC, allowing direct interfacing with higher-voltage logic families. Output VOL is specified down to 0.55 V at 16 mA and 4.5 V V_CC, and propagation delay ranges from 3.4 ns to 7.2 ns (V_CC = 5 V, C_L = 15 pF), supporting reliable timing in mixed-signal systems.

FAQ

What is the maximum sink current supported by SN74LV07APWRG4 at 3.3-V supply?

The SN74LV07APWRG4 supports up to 8 mA sink current (I_OL) at V_CC = 3 V–3.6 V, as specified in Section 7.3 of the datasheet. This value defines the minimum allowable pull-up resistance for maintaining valid VOH under load, and must be derated at elevated temperatures per thermal characteristics in Section 7.4.

Does SN74LV07APWRG4 support hot-swap or partial power-down operation?

Yes, SN74LV07APWRG4 includes I_off circuitry that disables outputs when V_CC = 0 V, limiting I_off to 5 µA maximum. This prevents back-current flow through powered inputs or outputs during hot-insertion or staggered power sequencing-critical for modular backplane and server applications.

Can SN74LV07APWRG4 inputs be driven by 5-V TTL logic while operating at 3.3-V VCC?

Yes, SN74LV07APWRG4 inputs tolerate voltages up to 5.5 V regardless of V_CC level. When V_CC = 3.3 V, a 5-V TTL input remains within absolute maximum ratings and meets VIH/VIL thresholds (VIH ≥ 2.31 V, VIL ≤ 0.99 V per Section 7.9), enabling direct interfacing without external resistors or clamps.

What is the recommended pull-up resistor value for SN74LV07APWRG4 driving a 5-V bus?

For a 5-V pull-up with maximum 0.55 V VOL at 16 mA (V_CC = 4.5–5.5 V), the minimum R_PULLUP is (5 V − 0.55 V)/16 mA ≈ 278 Ω. A standard 330-Ω resistor ensures margin for temperature drift and process variation while maintaining <1% bus capacitance impact per TI application guidance.

Is SN74LV07APWRG4 pin-compatible with other TSSOP-14 hex buffer variants?

SN74LV07APWRG4 shares identical TSSOP-14 pinout and function mapping with SN74LV07APWR and SN74LV07APWRG3. However, G4 suffix denotes NiPdAu lead finish per JEDEC standards, differing from G3 (pure Sn) and base PWR (NIPDAU/Sn mix); solderability and RoHS compliance remain equivalent across these variants.
