SN74HCT541DBR

Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SSOP-20-208mil

SN74HCT541DBR from Texas Instruments, in a SSOP-20-208mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OE1 input Active-low output enable 1; if OE1 or OE2 is high, all eight outputs are in the high-impedance state.
2 A1 input Buffer data input 1, TTL-compatible with VIH min 2 V and VIL max 0.8 V.
3 A2 input Buffer data input 2, TTL-compatible with VIH min 2 V and VIL max 0.8 V.
4 A3 input Buffer data input 3, TTL-compatible with VIH min 2 V and VIL max 0.8 V.
5 A4 input Buffer data input 4, TTL-compatible with VIH min 2 V and VIL max 0.8 V.
6 A5 input Buffer data input 5, TTL-compatible with VIH min 2 V and VIL max 0.8 V.
7 A6 input Buffer data input 6, TTL-compatible with VIH min 2 V and VIL max 0.8 V.
8 A7 input Buffer data input 7, TTL-compatible with VIH min 2 V and VIL max 0.8 V.
9 A8 input Buffer data input 8, TTL-compatible with VIH min 2 V and VIL max 0.8 V.
10 GND power_in Ground reference for the device.
11 Y8 tri_state Three-state true-data output 8 with ±6 mA drive at 5 V, high-impedance when either OE is high.
12 Y7 tri_state Three-state true-data output 7 with ±6 mA drive at 5 V, high-impedance when either OE is high.
13 Y6 tri_state Three-state true-data output 6 with ±6 mA drive at 5 V, high-impedance when either OE is high.
14 Y5 tri_state Three-state true-data output 5 with ±6 mA drive at 5 V, high-impedance when either OE is high.
15 Y4 tri_state Three-state true-data output 4 with ±6 mA drive at 5 V, high-impedance when either OE is high.
16 Y3 tri_state Three-state true-data output 3 with ±6 mA drive at 5 V, high-impedance when either OE is high.
17 Y2 tri_state Three-state true-data output 2 with ±6 mA drive at 5 V, high-impedance when either OE is high.
18 Y1 tri_state Three-state true-data output 1 with ±6 mA drive at 5 V, high-impedance when either OE is high.
19 OE2 input Active-low output enable 2; if OE1 or OE2 is high, all eight outputs are in the high-impedance state.
20 VCC power_in Supply voltage, 4.5 V to 5.5 V recommended, with a 0.1-µF bypass capacitor placed close to the pin.
