简介

The ZT308xE series devices are 5V 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 ZT308xE series devices spans out with half or full duplex, data rate guaranteed at 250Kbps, 1Mbps, or 20Mbps and allow one-eighth of an 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).

规格:

● Meets or exceeds the requirements of ANSI Standard TIA/EIA-485-A and ISO 8482:1987(E) specifications for V cc at +5V ±10%
● Low quiescent current: 0.4mA typ., 0.9mA max
● Low shutdown current (where applicable): 1nA typical, 10μA max
● Guaranteed standard data rate 250Kbps, 1Mbps, or 20Mbps
● True Fail-Safe (Open, Short, Bus Idle) Receiver
● -7V to +12V common-mode input voltage range
● Half-Duplex or Full-Duplex mode 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)
● Alternative replacement for MAX308xE series, SN75HVD3082E, and SN65HVD3082E series
