80C51BHP 技术参数

87C51/80C51BH/80C31BH

NOTES:

1. ‘‘Typicals’’ are based on a limited number of samples taken from early manufacturing lots and are not guaranteed. The

values listed are at room temp, 5V.

2. Capacitive loading on Ports 0 and 2 may cause noise pulses above 0.4V to be superimposed on the V s of ALE and

Ports 1, 2 and 3. The noise is due to external bus capacitance discharging into the Port 0 and Port 2 pins when these pins

change from 1 to 0. In applications where capacitive loading exceeds 100 pF, the noise pulses on these signals may exceed

0.8V. It may be desirable to qualify ALE or other signals with a Schmitt Trigger, or CMOS-level input logic.

3. Capacitive loading on Ports 0 and 2 may cause the V

cation when the address bits are stabilizing.

on ALE and PSEN to momentarily fall below the 0.9V

specifi-

4. See Figures 6 through 8 for I

test conditions. Minimum V

for Power Down is 2V.

5. Under steady state (non-transient) conditions, I must be externally limited as follows:

Maximum I per port pin:

Maximum I per 8-bit portÐ

10 mA

Port 0: 26 mA

Ports 1, 2, and 3: 15 mA

Maximum total I for all output pins: 71 mA

If I exceeds the test condition, V may exceed the related specification.

OL OL

Pins are not guaranteed to sink greater than the listed test conditions.
