Translators Link Low Voltage ASICs To High Voltage Devices March 2002 Issue Published Date: March 01, 2002
Capable of interfacing ASICs operating on voltages to 1.2V with peripherals operating on voltages to 5.5V, the MAX3372E to 3379E and MAX3390E to 3393E dual/quad logic-level translation ICs include ESD protection to ±15 kV on their I/O VCC pins. Depending on the device, features include power consumption of less than 100 µA of quiescent current, a 0.3 µA three-state mode, and 2.5V to 5.5V operation and 1.2V to VCC logic supply. As to operating speeds, MAX3372E/3377E are slew-rate limited and operate up to 250 kbps, while the other devices operate up to 16-Mbps when used with an active driver and up to 500 kb/s with an open-drain driver. The translators have a -40¡C to 85¡C operating temperature range and come in 3 x 3 and 4 x 3 UCSPs and 8-pin SOT 23s. Prices start at $0.90 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA.
