INDUSTRIAL TEMPERATURE RANGE
IDT74CBTLV16212
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 CBTLV16212 provides a set of 24 high-speed switches for bus
exchanging and switching. The device has low ON resistance, resulting
in under 250ps propagation delay through the switch. The CBTLV16212
operates as a single 24-bit bus switch or as a 12-bit bus exchanger, which
provides data exchanging between the four signal ports through the data
select (S0-S2) pins.
The CBTLV16212 has the break-before-make feature, which allows
zero current when switching between ports B1 and B2.
APPLICATIONS:
• 3.3V High Speed Bus Switching and Bus Isolation
