Texas Instruments SN74LVC1G07DBVTE4

Overview

SN74LVC1G07DBVTE4 from Texas Instruments is a single non-inverting buffer/driver with open-drain output, designed for 1.65V–5.5V V_CC operation. It delivers 32mA sink current at 4.5V, supports 5.5V-tolerant inputs/outputs, and achieves 4.2ns max propagation delay at 3.3V - enabling wired-OR logic and level translation in space-constrained consumer audio and embedded interfaces.

For engineers reviewing the SN74LVC1G07DBVTE4 datasheet, SN74LVC1G07DBVTE4 pinout, SN74LVC1G07DBVTE4 application, or SN74LVC1G07DBVTE4 equivalent, key selection criteria include open-drain drive strength (32mA), I_off partial-power-down support, 5-pin SOT-23 (DBV) package compatibility, and 5.5V input tolerance across 1.65–5.5V supply range.

Technical Context

The SN74LVC1G07DBVTE4 implements a single CMOS buffer stage with an open-drain output stage capable of sinking up to 32mA, enabling active-low wired-OR and active-high wired-AND bus configurations. Its I_off circuitry actively disables outputs when V_CC = 0V, preventing back-drive and supporting live insertion.

It operates across –40°C to +125°C ambient temperature and accepts input voltages up to 5.5V regardless of V_CC level - allowing bidirectional voltage translation between 1.65V, 1.8V, 2.5V, 3.3V, and 5V domains. Propagation delay remains ≤4.7ns over full temperature range at 3.3V.

FAQ

What is the maximum sink current capability of the SN74LVC1G07DBVTE4?

The SN74LVC1G07DBVTE4 provides a maximum sink current (I_OL) of 32mA when V_CC = 4.5V, as specified in the Electrical Characteristics table under Recommended Operating Conditions. This rating applies across the full operating temperature range (–40°C to +125°C) and enables direct driving of LEDs, pull-up networks, and wired-OR bus loads without external amplification. The SN74LVC1G07DBVTE4 maintains this performance while consuming only 10µA typical quiescent current.

Does the SN74LVC1G07DBVTE4 support level translation between different supply voltages?

Yes, the SN74LVC1G07DBVTE4 supports bidirectional level translation: its inputs accept voltages up to 5.5V regardless of V_CC, and its open-drain output can be pulled up to any voltage ≤5.5V. For example, with V_CC = 1.8V, the SN74LVC1G07DBVTE4 can translate a 3.3V input signal to a 3.3V-wired-OR bus. This eliminates external level-shifting components in mixed-voltage systems like AV receivers and SSD controllers.

What is the purpose of the NC pin on the SN74LVC1G07DBVTE4?

Pin 1 of the SN74LVC1G07DBVTE4 is designated NC (No internal connection) - it is an unconnected die pad with no electrical function. Per TI's layout guidance, this pin may be left floating or tied to GND for mechanical stability and EMI reduction. It must never be connected to V_CC or driven, as it has no internal bonding. The SN74LVC1G07DBVTE4's functional pins (A, GND, Y, V_CC) remain fully compatible with standard SOT-23-5 routing.

How does the I_off feature benefit system design with the SN74LVC1G07DBVTE4?

The I_off feature in the SN74LVC1G07DBVTE4 disables output leakage when V_CC = 0V, limiting current to ±10µA even with 5.5V applied to inputs or outputs. This prevents back-driving powered-down sections during hot-swap events - critical in modular systems like audio docks and GPS navigation devices. Unlike standard buffers, the SN74LVC1G07DBVTE4 ensures safe isolation without external blocking diodes or complex power sequencing.

What is the propagation delay specification for the SN74LVC1G07DBVTE4 at 3.3V?

The SN74LVC1G07DBVTE4 has a maximum propagation delay (t_pd) of 4.2ns at V_CC = 3.3V, TA = 25°C, as documented in Section 5.6 of the datasheet. Over the full industrial temperature range (–40°C to +125°C), t_pd increases to 4.7ns max at 3.3V. This consistent, low-latency response supports reliable timing in high-speed control paths such as interrupt aggregation in network projectors and SSD command decoding.
