Description
MC74HCT541ADWG is an octal (8-bit) non-inverting buffer/line driver with 3-state (tri-state) outputs in the HCT family. It buffers eight data inputs (D0–D7) to eight outputs (Q0–Q7) and uses a single output-enable input (G) to put all outputs into high impedance when desired. The inputs are TTL/CMOS-compatible, and the device runs from a +4.5 V to +5.5 V supply (typical 5 V). The “ADWG” suffix denotes a specific packaging/temperature/ RoHS variant (e.g., a 20-pin surface-mount package with standard temperature range) per the manufacturer’s options.
Key uses:
- Interfaces between a microprocessor/MEMORY and peripheral devices
- Bus buffering and isolation on data/address lines
- Situations where an 8-bit bus must be tri-stated or shared
In short: an 8-bit, non-inverting buffer with a global tri-state enable, suitable for fast, TTL-to-CMOS-compatible bus interfacing in 5V systems.

Pinout
- Pin count: 20 pins (20-pin package)
- Function: Octal buffer/driver with 3-state outputs. It provides eight non-inverting buffers (A0–A7 to Y0–Y7) with a single active-low output-enable input (OE/G). When OE is low, outputs reflect the inputs; when OE is high, all outputs are high-impedance.
