2001 Nov 08 853-2303 27312
FEATURES
• 5 Ω switch connection between two ports
• TTL compatible control input levels
• Designed to be used in level shifting applications
• Package options include plastic shrink small outline (SSOP) and
thin shrink small outline (TSSOP)
• Latch-up testing is done to JESDEC Standard JESD78 which
exceeds 100 mA
• ESD protection exceeds 1500 V HBM per JESD22-114A and
1000 V CDM per JESD22-C101
DESCRIPTION
The CBTD16213 provides 24 bits of high-speed TTL-compatible bus
switching or exchanging. The low on-state resistance of the switch
allows connections to be made with minimal propagation delay.
A diode to V
CC
is integrated into the circuit to allow for level shifting
between 5 V inputs and 3.3 V outputs.
The CBTD16213 operates as 24-bit bus switch or a 12-bit bus
exchanger, which provides data exchanging between the four signal
ports via the data-select (S0–S2) terminals.
The CBTD16213 is characterized for operation from –40 to +85 °C.
