CY74FCT244TSOCT

Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SOIC-20-300mil

CY74FCT244TSOCT from Texas Instruments, in a SOIC-20-300mil. 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 OEA input Active-low output enable for the A bank (OA0-OA3); outputs are high-impedance when OEA is high, and unused inputs must be held at VCC or GND.
2 DA0 input Data input A0, TTL-compatible with VIH min 2 V and VIL max 0.8 V, buffered to OA0.
3 OB0 tri_state 3-state output B0 following DB0, with 64 mA sink and 32 mA source drive for CY74FCT244T.
4 DA1 input Data input A1, TTL-compatible with VIH min 2 V and VIL max 0.8 V, buffered to OA1.
5 OB1 tri_state 3-state output B1 following DB1, with 64 mA sink and 32 mA source drive for CY74FCT244T.
6 DA2 input Data input A2, TTL-compatible with VIH min 2 V and VIL max 0.8 V, buffered to OA2.
7 OB2 tri_state 3-state output B2 following DB2, with 64 mA sink and 32 mA source drive for CY74FCT244T.
8 DA3 input Data input A3, TTL-compatible with VIH min 2 V and VIL max 0.8 V, buffered to OA3.
9 OB3 tri_state 3-state output B3 following DB3, with 64 mA sink and 32 mA source drive for CY74FCT244T.
10 GND power_in Ground reference for the device.
11 DB3 input Data input B3, TTL-compatible with VIH min 2 V and VIL max 0.8 V, buffered to OB3.
12 OA3 tri_state 3-state output A3 following DA3, with 64 mA sink and 32 mA source drive for CY74FCT244T.
13 DB2 input Data input B2, TTL-compatible with VIH min 2 V and VIL max 0.8 V, buffered to OB2.
14 OA2 tri_state 3-state output A2 following DA2, with 64 mA sink and 32 mA source drive for CY74FCT244T.
15 DB1 input Data input B1, TTL-compatible with VIH min 2 V and VIL max 0.8 V, buffered to OB1.
16 OA1 tri_state 3-state output A1 following DA1, with 64 mA sink and 32 mA source drive for CY74FCT244T.
17 DB0 input Data input B0, TTL-compatible with VIH min 2 V and VIL max 0.8 V, buffered to OB0.
18 OA0 tri_state 3-state output A0 following DA0, with 64 mA sink and 32 mA source drive for CY74FCT244T.
19 OEB input Active-low output enable for the B bank (OB0-OB3); outputs are high-impedance when OEB is high, and unused inputs must be held at VCC or GND.
20 VCC power_in Supply voltage, 4.75 V to 5.25 V recommended for CY74FCT244T (absolute maximum -0.5 V to 7 V).
