FEATURES: • Bus switches provide zero delay paths • Extended commercial range of –40°C to +85°C • Low switch on-resistance: FST163xxx – 5Ω FST1632xxx — 28Ω • TTL-compatible input and output levels • ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) • Available in SSOP, TSSOP and TVSOP DESCRIPTION: The FST163384/1632384 belong 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. These devices connect input and output ports through an n-channel FET. When the gate-to-source junction of this FET is adequately forward-biased the device conducts and the resistance between input and output ports is small. Without adequate bias on the gate-to-source junction of the FET, the FET is turned off, therefore with no VCC applied, the device has hot insertion capability. The low on-resistance and simplicity of the connection between input and output ports reduces the delay in this path to close to zero. The FST1632xxx integrates terminating resistors in the device, thus eliminating the need for external 25Ω series resistors. The FST163384 and FST1632384 are 20-bit TTL-compatible bus switches. The BEx pins provide enable control.
