Nexperia · Global Sourcing Parts · TSSOP-20

74LVT2244PW from Nexperia, in a TSSOP-20. 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 1OE input Active-LOW output enable for bank 1 (outputs 1Y0-1Y3). LOW = outputs driven from 1A0-1A3; HIGH = outputs in high-impedance (Z) state. VIH ≥ 2.0 V, VIL ≤ 0.8 V.
2 1A0 input Bank 1 data input, channel 0. TTL-compatible logic input with bus-hold; drives 1Y0 when 1OE is LOW. Overvoltage-tolerant to 5.5 V.
3 2Y3 tri_state Bank 2 data output, channel 3. 3-state buffered copy of 2A3 with ~30 Ω integrated series termination. IOH = -12 mA, IOL = +12 mA. High-Z when 2OE is HIGH.
4 1A1 input Bank 1 data input, channel 1. TTL-compatible logic input with bus-hold; drives 1Y1 when 1OE is LOW. Overvoltage-tolerant to 5.5 V.
5 2Y2 tri_state Bank 2 data output, channel 2. 3-state buffered copy of 2A2 with ~30 Ω integrated series termination. IOH = -12 mA, IOL = +12 mA. High-Z when 2OE is HIGH.
6 1A2 input Bank 1 data input, channel 2. TTL-compatible logic input with bus-hold; drives 1Y2 when 1OE is LOW. Overvoltage-tolerant to 5.5 V.
7 2Y1 tri_state Bank 2 data output, channel 1. 3-state buffered copy of 2A1 with ~30 Ω integrated series termination. IOH = -12 mA, IOL = +12 mA. High-Z when 2OE is HIGH.
8 1A3 input Bank 1 data input, channel 3. TTL-compatible logic input with bus-hold; drives 1Y3 when 1OE is LOW. Overvoltage-tolerant to 5.5 V.
9 2Y0 tri_state Bank 2 data output, channel 0. 3-state buffered copy of 2A0 with ~30 Ω integrated series termination. IOH = -12 mA, IOL = +12 mA. High-Z when 2OE is HIGH.
10 GND power_in Ground (0 V) reference for the device. Connect to system ground with a low-inductance path.
11 2A0 input Bank 2 data input, channel 0. TTL-compatible logic input with bus-hold; drives 2Y0 when 2OE is LOW. Overvoltage-tolerant to 5.5 V.
12 1Y3 tri_state Bank 1 data output, channel 3. 3-state buffered copy of 1A3 with ~30 Ω integrated series termination. IOH = -12 mA, IOL = +12 mA. High-Z when 1OE is HIGH.
13 2A1 input Bank 2 data input, channel 1. TTL-compatible logic input with bus-hold; drives 2Y1 when 2OE is LOW. Overvoltage-tolerant to 5.5 V.
14 1Y2 tri_state Bank 1 data output, channel 2. 3-state buffered copy of 1A2 with ~30 Ω integrated series termination. IOH = -12 mA, IOL = +12 mA. High-Z when 1OE is HIGH.
15 2A2 input Bank 2 data input, channel 2. TTL-compatible logic input with bus-hold; drives 2Y2 when 2OE is LOW. Overvoltage-tolerant to 5.5 V.
16 1Y1 tri_state Bank 1 data output, channel 1. 3-state buffered copy of 1A1 with ~30 Ω integrated series termination. IOH = -12 mA, IOL = +12 mA. High-Z when 1OE is HIGH.
17 2A3 input Bank 2 data input, channel 3. TTL-compatible logic input with bus-hold; drives 2Y3 when 2OE is LOW. Overvoltage-tolerant to 5.5 V.
18 1Y0 tri_state Bank 1 data output, channel 0. 3-state buffered copy of 1A0 with ~30 Ω integrated series termination. IOH = -12 mA, IOL = +12 mA. High-Z when 1OE is HIGH.
19 2OE input Active-LOW output enable for bank 2 (outputs 2Y0-2Y3). LOW = outputs driven from 2A0-2A3; HIGH = outputs in high-impedance (Z) state. VIH ≥ 2.0 V, VIL ≤ 0.8 V.
20 VCC power_in Supply voltage input. Operating range 2.7 V to 3.6 V (absolute max +4.6 V). Decouple locally with a 100 nF ceramic capacitor to GND.
