TL16PC564B, TL16PC564BLV

PCMCIA UNIVERSAL ASYNCHRONOUS RECEIVER TRANSMITTER

SLLS225A – MARCH 1996 – REVISED FEBRUARY 1998

POST OFFICE BOX 655303

• DALLAS, TEXAS 75265

power consumption

The TL16PC564A has low power consumption under the following conditions:

• 32-MHz signal on XIN

• Divide-by-n is set to give a 1.8432-MHz UARTCLK signal

• Nominal data

• V

CC = 5 V

The current (ICC) and power consumption are 18 mA (typical) and 90 mW (typical), respectively. These current

and power figures fluctuate with changes in the above conditions.

† Stresses beyond those listed under “absolute maximum ratings” 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.

NOTES:

1. Applies for external input and bidirectional buffers. VI > VCC does not apply to fail-safe pins.

2. Applies for external output and bidirectional buffers. VO > VCC does not apply to fail-safe pins.

NOTES:

3. Meets TTL levels, VIHmin = 2 V and VILmax = 0.8 V on nonhysteresis inputs

4. Applies for external output buffers

5. RST, STSCHG, OUT1, and OUT2 are open-drain outputs, so IOH does not apply.

6. These junction temperatures reflect simulation conditions. Absolute maximum junction temperature is 150

°C. The customer is

responsible for verifying junction temperature.
