Overview
The Fairchild Semiconductor 74LVT2245SJX is a low voltage octal bidirectional transceiver featuring three-state outputs. It operates within a supply voltage range of 2.7V to 3.6V, supporting data transfer between two independent 8-bit buses. The device includes non-inverting logic and is housed in a 20-pin Small Outline Package (SOP). It is designed for surface mount installation and functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Octal bidirectional data bus transceiver with non-inverting functionality
- Three-state outputs for effective bus isolation and control
- Low voltage operation compatible with 3.3V systems
Applications
- Memory mapping controllers
- Clock drivers
- Bus-oriented communications
Procurement Notes
This component is obsolete and no longer in production by Fairchild Semiconductor or ON Semiconductor. Sourcing requires verification of authenticity and condition through authorized distributors or surplus suppliers. Ensure the specific suffix SJX matches the required 20-SOP package and RoHS compliance status before procurement.
Selection Notes
Select this part only if legacy compatibility with Fairchild/ON Semiconductor pinouts and electrical characteristics is mandatory. Verify that the 2.7V to 3.6V operating range meets system requirements. Consider modern equivalents if new designs allow, as availability is limited due to discontinuation status.
Part Context
The 74LVT2245 belongs to the LVT (Low Voltage TTL) family, bridging older logic standards with lower voltage applications. The SJX suffix denotes the specific 20-lead SOP package variant. This series was widely used in embedded systems requiring robust bidirectional data transfer at reduced power levels compared to standard 5V logic families.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the available documentation. Due to the obsolete status, direct replacements must be verified against pinout, voltage, and speed specifications by engineering teams.
