The 74ABT162240 is a high-performance BiCMOS device that combines low static and dynamic power dissipation with high speed. This device is an inverting 16-bit buffer that is ideal for driving bus lines. The device features four Output Enables (1OE, 2OE, 3OE, 4OE), each controlling four of the 3-State outputs. Two options are available, 74ABT162240 which does not have the bus hold feature and 74ABTH162240 which incorporates the bus hold feature.
This document is a product specification datasheet for the Philips 74ABT162240 and 74ABTH162240 integrated circuits. These are high-performance BiCMOS devices designed as 16-bit inverting buffers ideal for driving bus lines.
The device features four Output Enables, each controlling four of the 3-State outputs. It includes TTL input and output switching levels with a propagation delay typical value of 27 ns at Vcc = 5V. Two variants are available: the standard 74ABT162240 and the 74ABTH162240, which incorporates bus hold data inputs to eliminate the need for external pull-up resistors.
| Propagation delay (typical) | 27 ns |
|---|---|
| Input capacitance | 4 pF |
| Output capability (High) | +12mA/-32mA |
| Operating temperature range | -40°C to +85°C |
| Supply voltage (recommended) | 4.5V to 5.5V |
The 74ABTH162240 incorporates bus hold data inputs which eliminate the need for external pull up resistors, whereas the standard 74ABT162240 does not have this feature.
Yes, live insertion and extraction are permitted for these devices.
