Rated for 295 mA continuous output per channel, this buffer can drive cables directly or supply the dynamic current needed by a fast ADC reference input. The DDPAK package with exposed tab (TO-263-7) is designed to conduct heat to the PCB copper plane.
There is no direct pin-compatible replacement announced by TI. The closest functional peer in the same buffer class is the THS4215DRBT, which offers 970 V/µs slew rate and 350 MHz bandwidth but in a different package (SON-8). For a drop-in substitute, verify the pinout and thermal pad layout against your board.
The LMH6321TSX/NOPB has a slew rate of 2900 V/µs.
The LMH6321 is designed as a high-speed buffer for video line driving, ADC input buffering, cable drivers, and signal conditioning in test equipment, communications infrastructure, and industrial control systems where a 2900 V/µs slew rate and 295 mA output are needed.
