CY74FCT374ATQCT

Texas Instruments · Flip Flops · QSOP-20-150mil

CY74FCT374ATQCT from Texas Instruments, in a QSOP-20-150mil. 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

2	O0	tri_state	Data output 0 with 64-mA sink current and 32-mA source current.
3	D0	input	Data input 0, captured on rising edge of CP with 2-ns setup time.
4	D1	input	Data input 1, captured on rising edge of CP with 2-ns setup time.
5	O1	tri_state	Data output 1 with 64-mA sink current and 32-mA source current.
6	O2	tri_state	Data output 2 with 64-mA sink current and 32-mA source current.
7	D2	input	Data input 2, captured on rising edge of CP with 2-ns setup time.
8	D3	input	Data input 3, captured on rising edge of CP with 2-ns setup time.
9	O3	tri_state	Data output 3 with 64-mA sink current and 32-mA source current.
10	GND	power_in	Ground, logic reference potential.
11	CP	input	Clock input, buffered clock pulse with low-to-high transition capturing D inputs.
12	O4	tri_state	Data output 4 with 64-mA sink current and 32-mA source current.
13	D4	input	Data input 4, captured on rising edge of CP with 2-ns setup time.
14	D5	input	Data input 5, captured on rising edge of CP with 2-ns setup time.
15	O5	tri_state	Data output 5 with 64-mA sink current and 32-mA source current.
16	O6	tri_state	Data output 6 with 64-mA sink current and 32-mA source current.
17	D6	input	Data input 6, captured on rising edge of CP with 2-ns setup time.
18	D7	input	Data input 7, captured on rising edge of CP with 2-ns setup time.
19	O7	tri_state	Data output 7 with 64-mA sink current and 32-mA source current.
20	VCC	power_in	Supply voltage 4.75 to 5.25 V.
