This document describes the features and characteristics of high-speed differential receivers such as SN65LVDT32B, SN65LVDS32B, SN65LVDT3486B, SN65LVDS3486B, SN65LVDT9637B, and SN65LVDS9637B. These products comply with the ANSI EIA/TIA-644 standard, support signaling rates up to 400 Mbps, operate with a single 3.3V supply, have a common-mode input voltage range of -2V to 4.4V, differential input thresholds less than 50 mV with 50 mV of hysteresis over the entire common-mode input voltage range, integrated 110-Ω line termination resistors, propagation delay times of 4 ns (typical), active fail-safe feature ensuring a high-level output with no input, bus-pin ESD protection exceeding 15 kV HBM, inputs remaining high-impedance on power down, recommended maximum parallel rate of 200 M-Transfer/s. These products are available in a small-outline package with 1.27 mm terminal spacing.
The SN65LVDS and SN65LVDT families are high‑speed differential line receivers that operate from a single 3.3 V supply. They meet ANSI/TIA‑644 standards, provide integrated 110 Ω line‑termination, and include a fail‑safe circuit that drives a high‑level output within 600 ns after loss of the input signal.
The devices are offered in small‑outline packages, support a wide common‑mode input range (‑2 V to +5 V), and are rated for operation from –40 °C to 85 °C. Electrical and switching characteristics such as propagation delay, output skew, and ESD protection are detailed in the datasheet.
| Supply voltage range | 3.0 V – 3.6 V |
|---|---|
| Operating temperature range | ‑40 °C – 85 °C |
| Integrated line‑termination resistance | 110 Ω |
| Propagation delay (low‑to‑high output) | 2.5 ns – 6 ns |
| ESD protection (HBM) | 15 kV |
The devices operate from a single 3.3 V supply with a permissible range of 3.0 V to 3.6 V.
Typical propagation delay is 2.5 ns to 6 ns for both low‑to‑high and high‑to‑low transitions.
The inputs can withstand up to 15 kV human‑body model (HBM) and 600 V machine‑model discharges.
They are rated for operation from –40 °C to 85 °C.
