Triple-channel buffer for video and high-speed signal paths
The Texas Instruments THS7347IPHPR is a triple-channel buffer amplifier designed for video distribution, RGB/component video, and other high-speed signal conditioning where three matched channels are needed in one package. Its 550 MHz -3 dB bandwidth and 1200 V/µs slew rate handle high-resolution video formats without slew-rate limiting on fast edges. The 48-HTQFP (7x7) package keeps the footprint compact for multi-layer boards.
Slew rate and bandwidth — what they mean for signal integrity
The 1200 V/µs slew rate ensures the output can track a full-scale step with minimal distortion at high frequencies. For a 1 V peak-to-peak signal at 100 MHz, the required slew rate is about 630 V/µs, so this part has margin. The 550 MHz -3 dB bandwidth supports high-definition video up to 1080p and beyond, and also covers high-speed ADC driving or pulsed signal buffering where settling time matters.
Each channel can source or sink 110 mA, enough to drive a 75 Ω video load (roughly 35 mA peak) with headroom. The 90 mA total supply current for all three channels is reasonable for a triple high-speed buffer; budget the thermal dissipation in the 48-HTQFP package if all channels drive heavy loads continuously.
