The CBT3245 is an octal bus switch with output enable, providing eight bits of high-speed TTL-compatible bus switching. It is functionally equivalent to the QS3245 and has a standard '245-type pinout. The switch has a low on-state resistance, allowing for minimal propagation delay in connections. The CBT3245 is organized as one 8-bit switch. When the enable signal OE is low, the switch is on and connects port A to port B. When OE is high, the switch is open and a high-impedance state exists between the two ports. The CBT3245 operates in a temperature range of -40°C to 85°C.
The Philips CBT3245 is an octal bus switch with output enable designed for high-speed TTL-compatible applications. It features a standard '245-type pinout and a low on-state resistance of 5Ω, allowing connections with minimal propagation delay. The device is organized as one 8-bit switch where Port A connects to Port B when the Output Enable (OE) input is low, and enters a high-impedance state when OE is high.
| Switch connection resistance | 5Ω |
|---|---|
| Operating temperature range | -40°C to 85°C |
| Supply voltage (VCC) | 4.0V to 5.5V |
| High-level input voltage (VIH) | 2.0V |
| Low-level input voltage (VIL) | 0.8V |
It provides eight bits of high-speed TTL-compatible bus switching in a standard '245 device pinout.
When OE is low, Port A connects to Port B; when OE is high, the switch is open and a high-impedance state exists.
The device is available in plastic small outline (D), shrink small outline (DB), and thin shrink small outline (TSSOP) packages.
