Texas Instruments SN54LVTH244A Data Sheet
Summary
These octal buffers and line drivers are designed for low-voltage (3.3V) operation while providing robust mixed-mode signal capability up to a 5V TTL interface. Detailed in this manual, the device ensures reliable data transfer through features like hot-insertion support, high ESD protection (exceeding 2000V), and stable mixed-signal operation down to 2.7V. It is an essential component for electronics designers building complex signal buffering or line driving circuits requiring flexible voltage compatibility.

Frequently Asked Questions
Does this component support both 3.3V and 5V systems?
Yes, it is designed for low-voltage (3.3-V) operation but has the capability to provide a TTL interface to a 5-V system environment.
What resistor arrangement should be used when controlling the Output Enable (OE)?
To keep the outputs in a high-impedance state during power up or down, OE should be tied to V through a pullup resistor. Minimum values are determined by current-sinking capability.
Is it safe to use external resistors with the bus-hold circuitry?
No, using pullup or pulldown resistors with the internal bus-hold circuitry is specifically not recommended.
Can this device withstand repeated power loss and insertion cycles?
Yes, these devices are fully specified for hot-insertion applications and include power-up 3-state circuitry to prevent driver conflict during power cycling.
