Product specication
Octal Schmitt trigger buffer/line driver;
3-state; inverting
74HC/HCT7540
FEATURES
Inverting outputs
Schmitt trigger action on all data inputs
Output capability: bus driver
ICC category: MSI
GENERAL DESCRIPTION
The 74HC/HCT7540 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/HCT7540 are octal Schmitt trigger inverting
buffer/line drivers with 3-state outputs. The 3-state outputs
are controlled by the output enable inputs OE1 and OE2.
A HIGH on OEn causes the outputs to assume a high
impedance OFF-state.
The Schmitt trigger action in the data inputs transforms
slowly changing input signals into sharply defined
jitter-free output signals.
The “7540” is identical to the “540” but has hysteresis on
the data inputs.
QUICK REFERENCE DATA
GND = 0 V; Tamb =25 °C; tr =tf = 6 ns
Notes
1. CPD is used to determine the dynamic power dissipation (PD in W):
PD =CPD × VCC2 × fi +∑ (CL × VCC2 × fo) where:
fi = input frequency in MHz
fo = output frequency in MHz
∑ (CL × VCC2 × fo) = sum of outputs
CL = output load capacitance in pF
VCC = supply voltage in V
2. For HC the condition is VI = GND to VCC
For HCT the condition is VI = GND to VCC 1.5 V
