The document describes the MAX364 and MAX365 precision quad single-pole single-throw (SPST) analog switches. The MAX364 has four normally closed (NC) switches, and the MAX365 has four normally open (NO) switches. Both parts offer low-channel on-resistance (less than 85Ω), guaranteed to match within 2Ω between channels and to remain flat over the analog signal range (∆9Ω max). Both parts also offer low leakage (less than 500pA at +25°C and less than 4nA at +85°C) and fast switching (turn-on time less than 250ns and turn-off time less than 170ns). The MAX364/MAX365 are fabricated with Maxim’s new improved 44V silicon-gate process. Design improvements guarantee extremely low charge injection (10pC), low power consumption (35µW), and electro- static discharge (ESD) greater than 2000V. The 44V maximum breakdown voltage allows rail-to-rail analog signal handling capability. These monolithic switches operate with a single positive supply (+10V to +30V) or with split supplies (±4.5V to ±20V) while retaining CMOS-logic input compatibility and fast switching. CMOS inputs provide reduced input loading.
The MAX364 and MAX365 are precision, quad, single‑pole single‑throw (SPST) analog switches. The MAX364 provides four normally‑closed (NC) switches, while the MAX365 provides four normally‑open (NO) switches. Both devices feature low on‑resistance, tight channel matching, low charge injection, and fast switching.
These switches are fabricated with Maxim’s 44 V silicon‑gate process and can operate from a single positive supply (+10 V to +30 V) or bipolar supplies (±4.5 V to ±20 V). They are TTL/CMOS‑logic compatible, support rail‑to‑rail analog signals, and include ESD protection exceeding 2000 V.
