Overview
The BA7653AFV-E2 is a single-circuit video signal switcher manufactured by ROHM Semiconductor. It features one 3-input to 1-output switching circuit designed for display signals with sync-tip clamp input compatibility. The device operates within a supply voltage range of 4.0 V to 7.0 V and consumes approximately 5.0 mA at Vcc=5.0 V. Key electrical characteristics include a typical switching speed of 70 ns, a frequency response of 10 MHz (0 dB), and interchannel crosstalk of -70 dB at 4.43 MHz. It utilizes an SSOP-B8 package.
Feature Summary
- Supports low-value clamp capacitance as small as 3000 pF
- Enables superimposition due to fast switching speed and minimal noise
- Allows control pin voltage application without VCC voltage
- Features high input impedance configuration
Applications
- Video cassette recorders (VCR)
- Television sets
- Equipment utilizing display signals
Procurement Notes
Verify the specific suffix E2 corresponds to the embossed tape and reel packaging format containing 2500 pieces per reel. Confirm that the SSOP-B8 package dimensions match the required PCB footprint. Ensure the operating temperature range of -30°C to +80°C aligns with the target environment specifications before finalizing procurement orders.
Selection Notes
Select this component when a 3-input video switch is required for standard definition signals. The wide dynamic range and low crosstalk make it suitable for applications demanding signal integrity. Verify that the 4.0 V to 7.0 V supply voltage range matches the system power rails. Consider the thermal dissipation limits if operating near maximum ambient temperatures.
Part Context
This part belongs to the BA765x series of high-performance video signal switchers from ROHM. It shares functional similarities with the BA7654F and BA7652AF but specifically offers three inputs instead of two or mute capabilities. The AFV designation indicates the SSOP-B8 surface mount package variant.
Replacement Considerations
Direct replacements include the BA7653AF in SOP-8 packaging. For systems requiring only two inputs, the BA7654F may be used. If mute functionality is needed, the BA7652AF is an alternative within the same family.
