74HC7541; 74HCT7541
Octal Schmitt trigger buffer/line driver; 3-state
Rev. 7 — 4 March 2016
Product data sheet
1. General description
The 74HC7541; 74HCT7541 is an 8-bit 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
Non-inverting outputs
Low-power dissipation
Input levels:
For 74HC7541: CMOS level
For 74HCT7541: TTL level
Complies with JEDEC standard no. 7A
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
