Description

The ZT3070E series devices are 3V differential data line transceivers for RS485/RS422 communication that consist of one driver and one receiver with high level of ESD protection. They are designed for balanced transmission lines interface that meet ANSI standard TIA/EIA-485-A and ISO 8482:1987(E) specifications. The ZT3070E series devices span out with half or full duplex, data rate guaranteed at 250Kbps, 500Kbps or 16Mbps, and allow 1/8 unit load that fan out 256 devices sharing a common bus. The I/Os are enhanced-electrostatic discharge (ESD) protected, exceeding ±15Kv Human Body Model (HBM). Meets or exceeds the requirements of ANSI Standard TIA/EIA-485-A and ISO 8482:1987(E) specifications for Vcc at +3.3V ±10% Low quiescent current – 0.5mA typ., 1.5mA max Low shutdown current (where applicable) - 0.05μA typical, 10μA max Guaranteed standard data rate 250Kbps, 500Kbps, or 16Mbps True Fail-Safe (Open and Short) Receiver -7V to +12V common-mode input voltage range Half-Duplex or Full-Duplex configuration Allows up to 1/8 unit load (256 devices) on the same common bus Controlled driver output slew rate and receiver input filtering Active-high driver enable and active-low receiver enable ESD Protection on bus terminals ±15kV Human Body Model (HBM) Drop-in Replacements for MAX3070E, MAX3071E, MAX3072E, MAX3073E, MAX3075E, MAX3076E, MAX3077E, MAX3078E
