BL1555 - SPDT Analog Switch

General Description

The BL1555 is a Dual Wide-Bandwidth, fast singlepole double-throw (SPDT) CMOS switch featuring an On-Resistance of 0.3 ohm at VDD=5V and wide power supply range from 1.65V to 5.5V.

It can be used as an analog switch or as a low-delay bus switch.

Key Features

  • Wide Power Supply Range:1.65V to 5.5V.
  • Low On-Resistance: RON(NC) = 0.3Ω(VCC=5V) RON(NO) = 0.3Ω(VCC=5V).
  • Low On-Resistance Flatness: RFLAT(NC) = 0.08Ω(VCC=5V) RFLAT(NO) = 0.08Ω(VCC=5V).
  • -3dB Bandwidth: 33MHz.
  • Rail-to-Rail Signal Range.
  • High Off-Isolation: -66dB (f=100 kHz).
  • Crosstalk Rejection: -74dB.
  • Low Total Harmonic Distortion: 0.035%.
  • Available in MSOP10 and QFN1.8x1.4-10L packages.
