NOTES TO DC ELECTRICAL CHARACTERISTICS:
1. Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to VSS unless otherwise
noted.
2. Under steady state (non-transient) conditions, IOL must be externally limited as follows:
Maximum IOL per port pin:
10mA
(NOTE: This is 85°C spec.)
Maximum IOL per 8-bit port:
26mA
Maximum total IOL for all outputs:
67mA
If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed
test conditions.
3. Pins of ports 1 and 3 source a transition current when they are being externally driven from 1 to 0. The transition current reaches its
maximum value when VIN is approximately 2V.
4. Power-down ICC is measured with all output pins disconnected; port 0 = VCC; X2, X1 n.c.; RST = VSS.
5. Active ICC is measured with all output pins disconnected; X1 driven with tCLCH, tCHCL = 5ns, VIL = VSS + 0.5V, VIH = VCC – 0.5V; X2 n.c.;
RST = port 0 = VCC. ICC will be slightly higher if a crystal oscillator is used.
6. Idle ICC is measured with all output pins disconnected; X1 driven with tCLCH, tCHCL = 5ns, VIL = VSS + 0.5V, VIH = VCC – 0.5V; X2 n.c.;
port 0 = VCC; RST = VSS.
AC ELECTRICAL CHARACTERISTICS
Tamb = 0°C to +70°C or –40°C to +85°C, VCC = 5V ±10% for 87C751, VCC = 5V ±10% for 83C751, VSS = 0V1, 2
