SCLS104E – AUGUST 1984 – REVISED DECEMBER 2015 SNx4HC125 Quadruple Bus Buffer Gates With 3-State Outputs
1 Features 3 Description The SNx4HC125 device is a quadruple set of bus
buffer gates and features independent line drivers
with 3-state outputs. The SNx4HC125 is designed for
2-V to 6-V VCC operation. Each output is disabled
when the associated output-enable (OE) input is high. 1 Wide Operating Voltage Range of 2 V to 6 V
High-Current 3-State Outputs Interface Directly
With System Bus or Can Drive Up to 15 LSTTL
Loads
Low Power Consumption, 80-ВµA Maximum ICC
Typical tpd = 11 ns
В±6-mA Output Drive at 5 V
Low Input Current of 1 ВµA Maximum To ensure the high-impedance state during power up
or power down, OE should be tied to VCC through a
pullup resistor; the minimum value of the resistor is
determined by the current-sinking capability of the …
