Introduction
The Am7838 and Am8838 are quad high-speed drivers/receivers designed for bus-oriented data transmission systems interconnected by lines terminated with 120Ω impedance. External termination consists of a 180Ω resistor from the bus to the +5V logic supply and a 390Ω resistor from the bus to ground. The bus may be terminated at one or both ends. Low bus pin current allows up to 27 driver/receiver pairs to share a common bus. Bus loading remains unchanged when VCC = 0V. The receivers feature hysteresis design, significantly enhancing bus noise immunity. A two-input NOR gate is included in each package to simultaneously disable all drivers. Receiver performance is optimized for systems with bus rise and fall times ≤1.0μs/V.
Features
- 4 fully independent driver/receiver pairs per package
- Typical receiver input hysteresis: 1V
- Receiver hysteresis independent of receiver output load
- Guaranteed minimum bus noise immunity: 1.3V typical, 2V typical
- Temperature-insensitive receiver thresholds track bus logic levels
- Typical bus termination current: 20μA at normal VCC or VCC = 0V
- Open-collector driver outputs allow wired-OR connections
- High speed
- 74-series TTL-compatible drivers, disable inputs, and receiver outputs
- Advanced Schottky process
