On-resistance is 400 ohms max, and the it conducts current equally well in both directions. These muxes feature extremely low off leakages (less than 20pA at 25°C), and extremely low on-channel leakages (less than 50pA at 25°C). The new design offers guaranteed low charge injection (1.5pC typ) and electrostatic discharge (ESD) protection greater than 2000V, per method 3015.7. The 338 operates from a single 4.5V to 30V supply or from dual supplies of ±4.5V to ±20V. All control inputs (whether address or enable) are TTL compatible (0.8V to 2.4V) over the full specified temperature range and over the ±4.5V to ±18V supply range. Capable of surviving space environments, the 338 is ideal for satellite, spacecraft, and space probe missions. The patented radiation-hardened RAD-PAK® technology incorporates radiation shielding in the microcircuit package. It eliminates box shielding while providing required lifetime in orbit. This product is available up to Class S packaging and screening. 09.12.02 Rev 3 (858)503- 3000 Fax: (858) 503-3100 - www.maxwell.com All data sheets are subject to change without notice 1 ©2002 Maxwell Technologies Inc..

DRON = RON(MAX) - RON(MIN). 4. Leakage parameters are 100% tested at the maximum rated hot temperature and guaranteed at 25 oC. 5. Guaranteed by design. 6. Worst-case isolation is on channel 4 because of its proximity to the drain pin. Isolation = 20logVCOM/VNO, where VCOM = output and VNO = input to off switch. 09.12.02 Rev 3 All data sheets are subject to change without notice 4 ©2002 Maxwell Technologies Inc.
