CBTS3384

10-bit bus switch with 5-bit output enables

and Schottky undershoot protection

2002 Dec 13

FEATURES

•5 Ω switch connection between two ports

•TTL compatible control input and output levels

•Undershoot protection included to prevent shoot through level

changes

•Latch-up protection exceeds 500 mA per JESD78

•ESD protection exceeds 2000 V HBM per JESD22-A114,

200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101

DESCRIPTION

The CBTS3384 provides ten 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 CBTS3384 device is organized as two 5-bit bus switches with

separate output-enable (OE) inputs. When OE is LOW, the switch is

on and port A is connected to B. When OE is HIGH, the switch is

open and high-impedance state exists between the two ports.

The CBTS3384 is characterized for operation from -40 to +85 °C.

NOTES:

1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the

device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to

absolute-maximum-rated conditions for extended periods may affect device reliability.

2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction

temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.

3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

NOTES:

1. All typical values are at VCC = 5 V, Tamb = 25 °C.

2. This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.

3. Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. On-state resistance is

determined by the lowest voltage of the two (A or B) terminals.
