CBT3244A PHILIPS [NXP Semiconductors], CBT3244A Datasheet - Page 4

• Manufacturer Part Number: CBT3244A
• Description: Octal bus switch with quad output enables
• Manufacturer: PHILIPS [NXP Semiconductors]

1. All typical values are at V
2. This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
3. Measured by the voltage drop between the A and the B terminals at the indicated current through the switch.
1. This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical on-state

Octal bus switch with quad output enables
On-state resistance is determined by the lowest voltage of the two (A or B) terminals.
resistance of the switch and a load capacitance of 50 pF, when driven by an ideal voltage source (zero output impedance).
