Manufacturer:ST Description:All devices are guaranteed at a data rate of 460kbps. The transceivers have a proprietary low-dropout trans- mitter output stage enabling RS-232 compatible opera- tion from a +2.25V to +3.0V supply with a dual charge pump. The charge pump requires only four 0.1µF capacitors. The 74HC4052TTR8E/74HC4052TTR9E feature a logic- level output (READY) that asserts when the charge pump is regulating and the device is ready to begin transmitting. The 74HC4052TTR8E/74HC4052TTR9E achieve a 1µA supply current using Maxims revolutionary AutoShutdown Plus feature. These devices automatically enter a low-power shut- down mode when the RS-232 cable is disconnected or the transmitters of the connected peripherals are inactive for more than 30 seconds. They turn on again when they sense a valid transition at any transmitter or receiver input. AutoShutdown Plus saves power without changes to the existing BIOS or operating system. The 74HC4052TTRE also features a 1µA shutdown mode that can be entered by driving SHDN low. The 74HC4052TTREs receivers remain active while in shutdown mode, allowing external devices such as modems to be monitored using only 1µA supply current. These devices are available in space-saving packages: 74HC4052TTRE (16-pin SSOP and 20-pin TSSOP), 74HC4052TTRE/ 74HC4052TTR8E (20-pin SSOP and 20-pin TSSOP), and 74HC4052TTR9E (16-pin SSOP). |
