20-bit bus switch with 10-bit output enables
Product specification
CBT16210
FEATURES
• 5Ω switch connection between two ports
• TTL compatible control input levels
• Package options include shrink small outline (SSOP) and thin
shrink small outline (TSSOP)
• ESD exceeds: CDM 1000 V; HBM 2000 V
DESCRIPTION
The CBT16210 provides 20 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.
The device is organized as a dual 10-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 CBT16210 is characterized for operation from –40°C to +85°C.
