74HC7540; 74HCT7540  
Octal Schmitt trigger buffer/line driver; 3-state; inverting  
Rev. 6 — 4 August 2021  
Product data sheet  
1. General description  
The 74HC7540; 74HCT7540 is an 8-bit inverting buffer/line driver with Schmitt-trigger inputs and  
3-state outputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes  
the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This enables  
the use of current limiting resistors to interface inputs to voltages in excess of VCC. Schmitt trigger  
inputs transform slowly changing input signals into sharply defined jitter-free output signals.  
2. Features and benefits  
Wide supply voltage range from 2.0 to 6.0 V  
CMOS low power dissipation  
High noise immunity  
Unlimited input rise and fall times  
Latch-up performance exceeds 100 mA per JESD 78 Class II Level B  
Inverting outputs  
Input levels:  
For 74HC7540: CMOS level  
For 74HCT7540: TTL level  
Complies with JEDEC standards  
JESD8C (2.7 V to 3.6 V)  
JESD7A (2.0 V to 6.0 V)  
ESD protection:  
HBM JESD22-A114F exceeds 2000 V  
MM JESD22-A115-A exceeds 200 V  
Multiple package options  
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
