Integrated Device Technology, Inc.
IDT74FST3257 PRELIMINARY www.DataSheet4U.com
FEATURES:
• Bus switches provide zero delay paths • Extended commercial range of –40°C to +85°C • Low switch on-resistance: FST3xxx – 5Ω • TTL-compatible input and output levels • ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) • Available in QSOP and SOIC
DESCRIPTION:
The FST3257 belongs to IDT's family of Bus switches. Bus switch devices perform the function of connecting or isolating two ports without providing any inherent current sink or source
capability. Thus they generate little or no noise of their own while providing a low resistance path for an external driver.
