Description

74LCX245MTC is an 8‑bit bidirectional buffer/transceiver with 3‑state outputs. It has two 8‑bit buses (A0–A7 and B0–B7). A DIR input selects the data direction (A→B or B→A). An OE input enables/disables the outputs; when OE is high, all outputs are high‑impedance. It’s used to buffer or isolate data on shared buses between devices (microcontrollers, memory, peripherals) or to help level‑shift in mixed‑voltage systems. Belonging to the LCX family, it’s a low‑voltage CMOS part designed for fast operation with low power. The exact Vcc range depends on the variant (typically in the low‑voltage CMOS window; check the datasheet for the precise supply range). The MTC suffix denotes the package type (a 20‑pin surface‑mount package). In short: a convenient 8‑bit, bidirectional buffer with controllable direction and tri‑state outputs for bus interfacing.

Features

Here are concise features of the 74LCX245MTC:
- 8-bit bidirectional bus transceiver (octal) for transferring data between two buses
- Direction control input (DIR) selects data flow: A→B or B→A
- Output enable input (OE) to place outputs in high-impedance state (3-state)
- Non-inverting data path
- High-impedance when OE is inactive, enabling bus sharing and reducing contention
- CMOS low-power technology with typical low static/dynamic power
- Wide supply range suitable for 3.3V and 5V systems (CMOS-compatible input thresholds)
- Designed for fast bus interfacing and easy integration in inter-board or on-chip buses
- Available in MTC package variant
Note: Exact voltage range and electrical specs can vary by manufacturer; check the specific datasheet for your supplier.

Package

20-pin Small Outline Integrated Circuit (SOIC) package.

Pinout

- Pin count: 20 pins (MTC package).
- Function: Octal bidirectional bus transceiver with 3-state outputs. Data can move between A0–A7 and B0–B7 in either direction controlled by DIR, with outputs enabled/disabled by /OE (and standard Vcc/GND).

Manufacturer

- Manufacturer: NXP Semiconductors (formerly Philips Semiconductors).
- Company type: A Dutch multinational that designs and manufactures semiconductor devices and integrated circuits for electronics applications.

Application

- 8-bit bidirectional bus transceiver with tri-state I/Os
- Buffers/isolates data and address buses between a microprocessor/MCU and memory or peripherals
- Enables safe bus sharing and level shifting in mixed-voltage systems (e.g., 3.3V↔5V)
- Commonly used in microprocessor/memory interfaces, backplanes, LCD/ADC/DAC interfaces, and I/O expansion where bidirectional data flow is needed
