LOW-VOLTAGE 10-BIT
BUS-EXCHANGE SWITCH
INDUSTRIAL TEMPERATURE RANGE
IDT74CBTLV3383
FEATURES:
• 5Ω A/B bi-directional bus 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 SSOP, QSOP and TSSOP packages
DESCRIPTION:
The CBTLV3383 provides ten bits of high-speed bus switching or exchang-
ing with low on-switch resistance of the switch allowing connections to be made
with minimal propagation delay.
The device operates as a 10-bit bus switch or a 5-bit bus exchanger, which
provides swapping of the A and B pairs of signals. The bus-exchange function
is selected when BX is high and BE is low.
APPLICATIONS:
• 3.3V High Speed Bus Switching and Bus Isolation
• Crossbar Switching
