RS244YTSS20

Jiangsu RUNIC Tech · Buffers, Drivers, Receivers, Transceivers · TSSOP-20

RS244YTSS20 from Jiangsu RUNIC Tech, in a TSSOP-20. 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 1OE input Active-low output enable; pulling 1OE high places all outputs in 3-state mode, per the pin description on page 4.
2 1A0 input Data input for buffer channel 1A0; the recommended input voltage range is 0 V to 5.5 V.
3 2Y0 output Buffer output 2Y0 (3-state capable); the Y port is rated -0.5 V to VCC+0.5 V in the high or low state and ±50 mA continuous output current.
4 1A1 input Data input for buffer channel 1A1; the recommended input voltage range is 0 V to 5.5 V.
5 2Y1 output Buffer output 2Y1 (3-state capable); the Y port is rated -0.5 V to VCC+0.5 V in the high or low state and ±50 mA continuous output current.
6 1A2 input Data input for buffer channel 1A2; the recommended input voltage range is 0 V to 5.5 V.
7 2Y2 output Buffer output 2Y2 (3-state capable); the Y port is rated -0.5 V to VCC+0.5 V in the high or low state and ±50 mA continuous output current.
8 1A3 input Data input for buffer channel 1A3; the recommended input voltage range is 0 V to 5.5 V.
9 2Y3 output Buffer output 2Y3 (3-state capable); the Y port is rated -0.5 V to VCC+0.5 V in the high or low state and ±50 mA continuous output current.
10 GND power_in Ground reference for the device.
11 2A3 input Data input for buffer channel 2A3; the recommended input voltage range is 0 V to 5.5 V.
12 1Y3 output Buffer output 1Y3 (3-state capable); the Y port is rated -0.5 V to VCC+0.5 V in the high or low state and ±50 mA continuous output current.
13 2A2 input Data input for buffer channel 2A2; the recommended input voltage range is 0 V to 5.5 V.
14 1Y2 output Buffer output 1Y2 (3-state capable); the Y port is rated -0.5 V to VCC+0.5 V in the high or low state and ±50 mA continuous output current.
15 2A1 input Data input for buffer channel 2A1; the recommended input voltage range is 0 V to 5.5 V.
16 1Y1 output Buffer output 1Y1 (3-state capable); the Y port is rated -0.5 V to VCC+0.5 V in the high or low state and ±50 mA continuous output current.
17 2A0 input Data input for buffer channel 2A0; the recommended input voltage range is 0 V to 5.5 V.
18 1Y0 output Buffer output 1Y0 (3-state capable); the Y port is rated -0.5 V to VCC+0.5 V in the high or low state and ±50 mA continuous output current.
19 2OE input Active-low output enable; pulling 2OE high places all outputs in 3-state mode, per the pin description on page 4.
20 VCC power_in Supply voltage; the datasheet specifies 1.65 V ≤ VCC ≤ 5.5 V.
