Texas Instruments SN74LVC1G07DCKRE4

Overview

SN74LVC1G07DCKRE4 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 SN74LVC1G07DCKRE4 datasheet, SN74LVC1G07DCKRE4 pinout, SN74LVC1G07DCKRE4 application, or SN74LVC1G07DCKRE4 equivalent, key selection criteria include open-drain drive strength (32mA), I_off support for live insertion, 0.5mm-pitch SC70-5 package compatibility, and 5.5V input tolerance across 1.65–5.5V supply range.

Technical Context

The SN74LVC1G07DCKRE4 implements a single CMOS buffer stage with an open-drain NMOS output transistor - no internal pull-up - requiring external termination for logic high. Its I_off circuitry actively disables outputs when V_CC = 0V, blocking back-drive current and enabling partial-power-down system architectures.

It operates across –40°C to +125°C ambient temperature (SC70 package), supports voltage translation both up (e.g., 1.8V logic driving 3.3V bus) and down (e.g., 5V signal into 3.3V domain), and maintains 4.2ns t_pd at 3.3V while consuming ≤10µA I_CC in static operation.

FAQ

What is the maximum sink current supported by SN74LVC1G07DCKRE4?

SN74LVC1G07DCKRE4 supports up to 32mA sink current at V_CC = 4.5V, as specified in the Absolute Maximum Ratings table. This value is validated across –40°C to +125°C and enables direct LED driving or termination of multiple CMOS loads without external amplification. The device maintains this rating under continuous DC conditions with proper thermal management.

Does SN74LVC1G07DCKRE4 support level translation between different supply voltages?

Yes, SN74LVC1G07DCKRE4 supports bidirectional level translation: its 5.5V-tolerant inputs accept signals up to 5.5V regardless of V_CC, and its open-drain output can be pulled up to any voltage ≤5.5V. For example, a 1.8V microcontroller output can drive SN74LVC1G07DCKRE4's A input, while Y is pulled to 3.3V - achieving upward translation without additional components.

Can SN74LVC1G07DCKRE4 be used in hot-swap or partial-power-down systems?

Yes, SN74LVC1G07DCKRE4 includes I_off circuitry that disables output drivers when V_CC = 0V, limiting I_off to ±10µA. This prevents back-current flow from powered sections into unpowered ones - a critical requirement for hot-pluggable modules such as USB-C audio docks or modular SSD enclosures where SN74LVC1G07DCKRE4 manages shared reset or interrupt lines.

What is the operating temperature range for SN74LVC1G07DCKRE4?

SN74LVC1G07DCKRE4 is rated for –40°C to +125°C ambient operation when packaged in SC70 (DCK), as confirmed in the Recommended Operating Conditions table. This full industrial temperature range qualifies it for under-hood automotive modules, industrial HMIs, and high-reliability storage controllers - unlike commercial-grade alternatives limited to +85°C.

How does the open-drain output of SN74LVC1G07DCKRE4 enable wired-OR functionality?

The open-drain Y output of SN74LVC1G07DCKRE4 connects directly to other open-drain outputs via a shared pull-up resistor. When any device pulls Y low, the net line goes low - implementing active-low wired-OR logic. This is commonly used for shared interrupt buses in SSDs or multi-sensor nodes, where SN74LVC1G07DCKRE4 isolates each source while maintaining electrical compatibility and noise immunity.
