74FCT244CTSOG8

RENESAS · Buffers, Drivers, Receivers, Transceivers · SOIC-20-300mil

74FCT244CTSOG8 from RENESAS, in a SOIC-20-300mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OEA input Active-LOW 3-state output enable for bank A (drives DA0-DA3 to OA0-OA3). When HIGH the OA0-OA3 outputs are placed in high-impedance (Z).
2 DA0 input Data input to bank A, buffer 0. Drives OA0 when OEA is LOW. TTL-compatible input (VIH >= 2 V, VIL <= 0.8 V).
3 OB0 tri_state 3-state buffered output from bank B, buffer 0 (driven by DB0). Enabled when OEB is LOW; high-impedance when OEB is HIGH. High-drive output (-15 mA IOH / 64 mA IOL).
4 DA1 input Data input to bank A, buffer 1. Drives OA1 when OEA is LOW. TTL-compatible input.
5 OB1 tri_state 3-state buffered output from bank B, buffer 1 (driven by DB1). Enabled when OEB is LOW.
6 DA2 input Data input to bank A, buffer 2. Drives OA2 when OEA is LOW. TTL-compatible input.
7 OB2 tri_state 3-state buffered output from bank B, buffer 2 (driven by DB2). Enabled when OEB is LOW.
8 DA3 input Data input to bank A, buffer 3. Drives OA3 when OEA is LOW. TTL-compatible input.
9 OB3 tri_state 3-state buffered output from bank B, buffer 3 (driven by DB3). Enabled when OEB is LOW.
10 GND power_in Device ground reference (0 V).
11 DB3 input Data input to bank B, buffer 3. Drives OB3 when OEB is LOW. TTL-compatible input.
12 OA3 tri_state 3-state buffered output from bank A, buffer 3 (driven by DA3). Enabled when OEA is LOW.
13 DB2 input Data input to bank B, buffer 2. Drives OB2 when OEB is LOW. TTL-compatible input.
14 OA2 tri_state 3-state buffered output from bank A, buffer 2 (driven by DA2). Enabled when OEA is LOW.
15 DB1 input Data input to bank B, buffer 1. Drives OB1 when OEB is LOW. TTL-compatible input.
16 OA1 tri_state 3-state buffered output from bank A, buffer 1 (driven by DA1). Enabled when OEA is LOW.
17 DB0 input Data input to bank B, buffer 0. Drives OB0 when OEB is LOW. TTL-compatible input.
18 OA0 tri_state 3-state buffered output from bank A, buffer 0 (driven by DA0). Enabled when OEA is LOW.
19 OEB input Active-LOW 3-state output enable for bank B (drives DB0-DB3 to OB0-OB3). When HIGH the OB0-OB3 outputs are placed in high-impedance (Z).
20 VCC power_in Positive supply, 5.0 V nominal (industrial: 5.0 V +/-5%; military: 5.0 V +/-10%). Bypass locally with a decoupling capacitor.
