Philips Semiconductors Product specification
Quad buffer/line driver; 3-state 74HC/HCT125
FEATURES Output capability: bus driver ICC category: MSI
GENERAL DESCRIPTIONThe 74HC/HCT125 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL).
They are specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT125 are four non-inverting buffer/line drivers with 3-state outputs. The 3-state outputs (nY) are controlled
by the output enable input (nOE). A HIGH at nOE causes the outputs to assume a HIGH impedance OFF-state.
The “125” is identical to the “126” but has active LOW enable inputs.
QUICK REFERENCE DATAGND = 0 V; Tamb = 25 °C; tr = tf = 6 ns
Notes CPD is used to determine the dynamic power dissipation (PDin μW): = CPD× VCC2×fi+∑ (CL× VCC2×fo) where: = input frequency in MHz = output frequency in MHz= output load capacitance in pF
VCC= supply voltage in V (CL× VCC2×fo) = sum of outputs For HC the condition is VI = GND to VCC
For HCT the condition is VI = GND to VCC− 1.5 V
