概述
Description
FXL4TD245UMX is an 8-bit, bidirectional bus transceiver in a compact UMX package. It functions as a buffered link between two 8-bit buses, with tri-state outputs controlled by DIR and /OE signals. When /OE is active, data can flow from one side to the other in the direction specified by DIR; when /OE is inactive, both sides go high-impedance for bus sharing or isolation. It is used to interface different voltage domains, expand microcontroller I/O, and buffer memory or peripheral buses while protecting devices from contention. Typical features include eight data lines (A0–A7 to B0–B7), tri-state operation, and a direction control mechanism suitable for level shifting between domains. The part comes in a small UMX package for compact designs. For exact electrical specs (voltage ranges, timing, pinout, and package details) refer to the manufacturer’s datasheet.
Equivalent
FXL4TD245UMX is an 8-bit, bidirectional, tri-state bus transceiver (octal 245). Direct equivalents exist in the 74xx245 family across vendors. Common cross-refs: TI SN74HC245 / SN74HCT245; NXP/ST/Onsemi 74HC245 / 74HCT245 (and variants such as 74LVX245, 74VHC245). Note: pinout and Vcc ranges vary (3.3V/5V); ensure package and voltage match your design.
Pinout
- Pin count: 20 pins
- Function: Octal bidirectional bus transceiver (A0–A7 / B0–B7) with 3-state outputs; DIR selects the data direction, and OE enables/disables the outputs.
