Datasheet Summary
BCT4257 Low-Voltage,2.8 Ω
SPDT Analog Switch
Low-Voltage, 2.8Ω SPDT Analog Switch
General Description
The BCT4257 is a high-bandwidth, fast single pole double-throw (SPDT) CMOS switch. It can be used as an analog switch or as a low-delay bus switch. Specified over a wide operating power supply voltage range, 1.65V to 5.5V, the BCT4257 has a maximum ON resistance of 5.1-ohms at 1.65V, 3.9-ohms at 2.3V & 2.85-ohms at 4.5V.
Break-before-make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching.
The control input, S, tolerates input drive signals up to 5.5V, independent of supply voltage.
