AiP74HC373TA20.TR

Wuxi I-core Elec · Latches · TSSOP-20

AiP74HC373TA20.TR from Wuxi I-core Elec, 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 OE input 3-state output enable input (active LOW); a HIGH on OE puts the outputs into the high-impedance OFF-state and does not affect the latch contents.
2 Q0 tri_state 3-state latch output.
3 D0 input Data input to latch 0 (inputs include clamp diodes).
4 D1 input Data input to latch 1 (inputs include clamp diodes).
5 Q1 tri_state 3-state latch output.
6 Q2 tri_state 3-state latch output.
7 D2 input Data input to latch 2 (inputs include clamp diodes).
8 D3 input Data input to latch 3 (inputs include clamp diodes).
9 Q3 tri_state 3-state latch output.
10 GND power_in Ground (0 V) reference for all voltages on the device.
11 LE input Latch enable input (active HIGH); when HIGH the latches are transparent, and when LOW they store the inputs present a set-up time before the HIGH-to-LOW transition.
12 Q4 tri_state 3-state latch output.
13 D4 input Data input to latch 4 (inputs include clamp diodes).
14 D5 input Data input to latch 5 (inputs include clamp diodes).
15 Q5 tri_state 3-state latch output.
16 Q6 tri_state 3-state latch output.
17 D6 input Data input to latch 6 (inputs include clamp diodes).
18 D7 input Data input to latch 7 (inputs include clamp diodes).
19 Q7 tri_state 3-state latch output.
20 VCC power_in Supply voltage: 2.0 V to 6.0 V for AiP74HC373 and 4.5 V to 5.5 V for AiP74HCT373, absolute maximum +7.0 V.
