Pinout

Pin Name Type Function
1 1D input Driver 1 logic input, with VIH of at least 2.0 V and VIL of at most 0.8 V (Table 4).
2 1Y output Driver 1 non-inverted bus output, which follows 1D when the driver is enabled (Table 12).
3 1Z output Driver 1 inverted bus output, which is complementary to 1Y when the driver is enabled (Table 12).
4 G input Active-high enable input: the drivers are enabled when G is high, and the outputs go high-impedance when G is low and /G is high (Table 12).
5 2Z output Driver 2 inverted bus output, which is complementary to 2Y when the driver is enabled (Table 12).
6 2Y output Driver 2 non-inverted bus output, which follows 2D when the driver is enabled (Table 12).
7 2D input Driver 2 logic input, with VIH of at least 2.0 V and VIL of at most 0.8 V (Table 4).
8 GND power_in Ground pin for the device.
9 3D input Driver 3 logic input, with VIH of at least 2.0 V and VIL of at most 0.8 V (Table 4).
10 3Y output Driver 3 non-inverted bus output, which follows 3D when the driver is enabled (Table 12).
11 3Z output Driver 3 inverted bus output, which is complementary to 3Y when the driver is enabled (Table 12).
12 /G input Active-low enable input: the drivers are enabled when /G is low (Table 12).
13 4Z output Driver 4 inverted bus output, which is complementary to 4Y when the driver is enabled (Table 12).
14 4Y output Driver 4 non-inverted bus output, which follows 4D when the driver is enabled (Table 12).
15 4D input Driver 4 logic input, with VIH of at least 2.0 V and VIL of at most 0.8 V (Table 4).
16 VCC power_in Power supply pin, with an operating range of 3.0 V to 5.5 V (Table 5).
