DS7838JA中文资料罗切斯特数据手册PDF规格书

Rochester Electronics has re-introduced and continues to manufacture critically needed semiconductors with the full authorization of the original manufacturer and an attention to quality that meets or exceeds the original component.

The Am7838 (and Am8838) are quad high-speed drivers/receivers designed for use in bus organized data transmission systems interconnected by terminated 120Ω impedance lines. The external termination is intended to be a 180Ω resistor from the bus to the +5V logic supply together with a 390Ω resistor from the bus to the ground.

The Am7838 features four totally separate drive/receiver pairs per package. The 1V typical receiver input hysteresis is independent of receiver output load.
