The MAX3095/MAX3096 are rugged, low-power, quad, RS-422/RS-485 receivers with electrostatic discharge (ESD) protection for use in harsh environments. All receiver inputs are protected to ±15kV using IEC 1000- 4-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model. The MAX3095 operates from a +5V supply, while the MAX3096 operates from a +3.3V supply. Receiver propagation delays are guaranteed to within ±8ns of a predetermined value, thereby ensuring device-to-device matching across production lots. Complementary enable inputs can be used to place the devices in a 1nA low-power shutdown mode in which the receiver outputs are high impedance. When active, these receivers have a fail-safe feature that guarantees a logic-high output if the input is open circuit. They also feature a quarter-unit-load input impedance that allows 128 receivers on a bus. The MAX3095/MAX3096 are pin-compatible, low-power upgrades to the industry-standard ’26LS32. They are available in a space-saving QSOP package.
The MAX3095 and MAX3096 are rugged, low‑power quad RS‑422/RS‑485 receivers offering up to +15 kV ESD protection per IEC 1000‑4‑2 standards. They operate from a +5 V supply (MAX3095) or a +3.3 V supply (MAX3096) and guarantee propagation‑delay matching of +8 ns and +10 ns respectively, enabling reliable high‑speed communication up to 10 Mbps.
These devices are pin‑compatible upgrades to the 26LS32, available in a space‑saving 16‑pin QSOP package. They support a low‑power shutdown mode drawing less than 1 nA, and their quarter‑unit‑load input impedance allows up to 128 receivers on a single RS‑485 bus. Typical applications include telecommunications equipment, rugged bus receivers, and level translators.
