Overview
The MAX3318CPWR is a low-power, full-duplex RS-232 transceiver manufactured by Texas Instruments. It integrates two drivers and two receivers within a single 20-pin TSSOP package. The device operates on a single 2.25V to 3V supply voltage and supports data rates up to 460Kbps. Key electrical parameters include a typical operating supply current of 2mA and an ESD protection rating of 15kV. The component features a shutdown mode for power conservation and includes receiver hysteresis of 300mV to improve noise immunity. It is designed for surface-mount installation with a specified operating temperature range of 0°C to 70°C.
Feature Summary
- Integrates dual drivers and dual receivers in a compact 20-TSSOP package
- Supports high-speed data transmission up to 460Kbps
- Includes dedicated shutdown pin for significant power reduction
- Provides robust 15kV ESD protection on all RS-232 lines
Applications
- Portable battery-powered devices requiring RS-232 connectivity
- Industrial control systems with limited power budgets
- Embedded communication interfaces in consumer electronics
Procurement Notes
Verify the specific suffix 'CPWR' confirms the commercial temperature grade (0°C to 70°C) and TSSOP-20 packaging. Confirm RoHS3 compliance status as indicated in official documentation. Ensure compatibility with standard 2.5V logic levels before integration into the design.
Selection Notes
Select this component when a low-voltage, single-supply RS-232 solution is required. Compare against the industrial grade variant MAX3318IPWR if operation below 0°C or above 70°C is necessary. Verify that the 460Kbps speed meets system requirements and that the 20-pin footprint fits the PCB layout constraints.
Part Context
This part belongs to the MAX3318 family of low-power RS-232 transceivers. It serves as a commercial-grade alternative to the industrial-rated MAX3318IPWR. The device is often compared with the TRS3318 series, which represents a later generation or pin-compatible successor in Texas Instruments' interface portfolio.
Replacement Considerations
MAX3318IPWR offers identical functionality with an extended industrial temperature range (-40°C to 85°C). TRS3318ECPWR is a related device but may have different qualification statuses; verify datasheet equivalence before substitution.
