Intersil Corporation Broadens its Portfolio of RS-232 Transmitters/Receivers with a Family of 3V Devices
Low supply current and automatic powerdown features assure long battery life
- Redesigned transmitter delivers high data rate
MELBOURNE, FL, December 2, 1999 – Manufacturers of PCs and PC peripherals as well as portable, battery operated appliances that require increased data communication speeds and low operational supply current drain can now look to Intersil for one of the broadest portfolios of low-voltage RS-232 transmitter-receivers on the market.
MELBOURNE, FL, December 2, 1999 Manufacturers of PCs and PC peripherals as well as portable, battery operated appliances that require increased data communication speeds and low operational supply current drain can now look to Intersil for one of the broadest portfolios of low-voltage RS-232 transmitter-receivers on the market.
Intersils new ICL3207- ICL3245 family delivers a comprehensive array of transmitter/receiver interface circuits that are highly suitable for portable, battery operated applications. The first two device types to be released in the series (ICL3241 and ICL3243) feature a redesigned transmitter circuit that effectively converts TTL/CMOS signal levels to RS-232 levels at guaranteed minimum data rates of 250k bits per second, essential for all applications where the RS-232 communications port constrains the data pipeline. This includes computers (laptops, palmtops), peripherals (printers and terminals), portable instrumentation (bar code readers and scanners) and high-speed modems. The Intersil guaranteed minimum data rate is nearly twice as fast as its major competitors (250 kbps vs. 120 kbps).
Additionally, this 3V family of products utilize only 0.3V of supply current during normal operation. The manual and automatic powerdown features increase battery life further, by reducing standby supply current to a 1 microamp trickle.
Component Features
The ICL3241 and ICL3243 feature a low power shutdown mode to conserve energy in battery-powered applications. Receivers remain active during shutdown, allowing for easy "wake up" capability. Additionally, the ICL3243 detects when the receiver inputs go to ground (disconnected RS-232 cable), and automatically places itself into the shutdown mode, without operating system intervention.
All Intersil drivers feature true TTL/CMOS input compatibility, slew rate-limited output and 300 power-off source impedance. The receivers can handle up to 30V input, and have a 3k to 7k input impedance. The receivers also feature hysteresis to greatly improve noise rejection.
Device Specifications
The ICL3241 AND ICL3243 meet the full spectrum of RS-232 performance specifications to accommodate a wide range of applications.
