Overview
The onsemi 74LCXR2245WM is an octal bus transceiver from the 74LCX logic family, housed in a 20-SOIC surface-mount package. It operates within a supply voltage range of 2 V to 3.6 V and supports LVTTL/TTL input levels with LVCMOS output levels. The device features non-inverting bidirectional data transfer with three-state outputs, providing drive currents of ±24 mA. It exhibits a propagation delay of 8 ns and functions reliably across an industrial temperature range of -40°C to +85°C.
Feature Summary
- Provides bidirectional data transmission for eight channels simultaneously
- Features three-state outputs to facilitate bus line management
- Supports mixed voltage interfaces between LVTTL/TTL inputs and LVCMOS outputs
Applications
- Memory module data bus interfacing
- Consumer electronics internal communication buses
