Rev. 1 — 6 June 2013
Product data sheet
1. General description
The 74AHC541-Q100; 74AHCT541-Q100 is a high-speed Si-gate CMOS device.
The 74AHC541-Q100; 74AHCT541-Q100 are octal non-inverting buffer/line drivers with
3-state bus compatible outputs.
The output enable inputs OE0 and OE1, control the 3-state outputs.
A HIGH on OEn causes the outputs to assume a high-impedance OFF-state.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
2. Features and benefits

5. Pinning information
5.1 Pinning
(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.
