BUS SWITCH
INDUSTRIAL TEMPERATURE RANGE
IDT74CBTLV16211
FEATURES:
• 5Ω A/B bi-directional switch
• Isolation Under Power-Off Conditions
• Over-voltage tolerant
• Latch-up performance exceeds 100mA
• VCC = 2.3V - 3.6V, normal range
• ESD >2000V per MIL-STD-883, Method 3015; >200V using
machine model (C = 200pF, R = 0)
• Available in TSSOP package
DESCRIPTION:
The CBTLV16211 operates as a single 24-bit bus switch or as a dual
12-bit bus switch, which provides high speed switching. This device has
very low ON resistance, resulting in under 250ps propagation delay
throughout the switch. When Output Enable (OE) is low, the corresponding
12-bit bus switch is on and port A is connected to Port B. When OE is high,
the switch is off and a high impedance exists between Port A and Port B.
To ensure the high-impedance state during power up or power down,
OE should be tied to VCC through a pullup resistor.
APPLICATIONS:
• 3.3V High Speed Bus Switching and Bus Isolation
