FEATURES
5 switch connection between two ports
TTL compatible control input levels
Designed to be used in level shifting applications
Package options include shrink small outline (SSOP) and
thin shrink small outline (TSSOP)
ESD protection exceeds 1000 V CDM per JESD22-C101
Latch-up testing is done to JESDEC Standard JESD78 which
exceeds 100 mA
DESCRIPTION
The CBTD16211 provides 24 bits of high-speed TTL-compatible bus
switching. The low on-state resistance of the switch allows
connections to be made with minimal propagation delay.
A diode to V
CC
is integrated in the circuit to allow for level shifting
between 5 V inputs and 3.3 V outputs.
The device is organized as a dual 12-bit bus switch with separate
output-enable (OE
) inputs. It can be used as two 10-bit bus switches
or as one 20-bit bus switch. When OE
is low, the associated 10-bit
bus switch is on, and port A is connected to port B. When OE
is
high, the switch is open, and a high-impedance state exists between
the ports.
The CBTD16211 is characterized for operation from –40 to +85 °C.
