DG201A Datasheet PDF – Quad SPST CMOS Analog Switch

Part Number : DG201A

Function : Quad SPST CMOS Analog Switch

Package : SOP, TSSOP, DIP 16 Pin

Manufacturers : Maxim Integrated

Pinouts :
DG201A datasheet

Description :

The DG201A and DG211 are normally closed, quad single-pole single-throw (SPST) analog switches. These CMOS switches can be continuously operated with power supplies ranging from ±4.5V to ±18V. Maxim guarantees that these switches will not latch up if the power supplies are disconnected with input signals still connected. Both devices have guaranteed break-before-make switching. The DG201A differs from the DG211 primarily in switching speeds. The DG201A has a maximum turn-off time of 450ns and a maximum turn-on time of 600ns. The DG211 has a maximum turn-off time of 500ns and a maximum turn-on time of 1000ns. Compared to the original manufacturer’s products, Maxim’s DG201A and DG211 consume significantly lower power making them better suited for portable applications. Maxim has also eliminated the need for the third (VL) power supply that is required for the operation of the original manufacturer’s DG211.

Features

1. Guaranteed ±4.5V to ±18V Operation
2. No VLSupply Required
3. Nonlatching with Supplies Turned Off and Input Signals Present
4. CMOS and TTL Logic Compatible
5. Monolithic, Low-Power CMOS Design

MAX232 datasheet pd

Description :

The MAX220, MAX232 Thru MAX249 family of line drivers/receivers is intended for all EIA/TIA-232E and V.28/V.24 communications interfaces, particularly applications where ±12V is not available.

These parts are especially useful in battery-powered systems, since their low-power shutdown mode reduces power dissipation to less than 5µW. The MAX225, MAX233, MAX235, and MAX245/MAX246/MAX247 use no external components and are recommended for applications where printed circuit board space is critical.

The MAX220-MAX249 are offered in 26 different packages with temperatures from 0 to +70°C up to -55°C to +125°C. See ordering information table at the end of the data sheet for all package and temperature options.

RS-232 Drivers
The typical driver output voltage swing is ±8V when loaded with a nominal 5kΩRS-232 receiver and VCC=+5V. Output swing is guaranteed to meet the EIA/TIA-232E and V.28 specification, which calls for ±5V minimum driver output levels under worst-case conditions. These include a minimum 3kΩload, VCC= +4.5V, and maximum operating temperature. Unloaded driver output voltage ranges from (V+ -1.3V) to (V- +0.5V).

RS-232 Receivers
EIA/TIA-232E and V.28 specifications define a voltage level greater than 3V as a logic 0, so all receivers invert. Input thresholds are set at 0.8V and 2.4V, so receivers respond to TTL level inputs as well as EIA/TIA-232E and V.28 levels. The receiver inputs withstand an input overvoltage up to ±25V and provide input terminating resistors with nominal 5kΩvalues. The receivers implement Type 1 interpretation of the fault conditions of V.28 and EIA/TIA-232E.
