CAXC4T245QBQBRQ1

Texas Instruments · Translators, Level Shifters · DHVQFN-16-EP(2.5x3.5)

CAXC4T245QBQBRQ1 from Texas Instruments, in a DHVQFN-16-EP(2.5x3.5). 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 VCCA power_in A-port supply voltage, specified for 0.65V ≤ VCCA ≤ 3.6V; the A port tracks VCCA and the control pins are referenced to it.
2 1DIR input Direction control input for port 1, referenced to VCCA; high sends data from A to B and low sends data from B to A when OE is low.
3 2DIR input Direction control input for port 2, referenced to VCCA; high sends data from A to B and low sends data from B to A when OE is low.
4 1A1 bidirectional Input/output 1A1 referenced to VCCA, operating over a 0.65V to 3.6V I/O range.
5 1A2 bidirectional Input/output 1A2 referenced to VCCA, operating over a 0.65V to 3.6V I/O range.
6 2A1 bidirectional Input/output 2A1 referenced to VCCA, operating over a 0.65V to 3.6V I/O range.
7 2A2 bidirectional Input/output 2A2 referenced to VCCA, operating over a 0.65V to 3.6V I/O range.
8 GND power_in Ground reference; the datasheet directs that the GND pins be grounded first.
9 GND power_in Ground reference; the datasheet directs that the GND pins be grounded first.
10 2B2 bidirectional Input/output 2B2 referenced to VCCB, operating over a 0.65V to 3.6V I/O range.
11 2B1 bidirectional Input/output 2B1 referenced to VCCB, operating over a 0.65V to 3.6V I/O range.
12 1B2 bidirectional Input/output 1B2 referenced to VCCB, operating over a 0.65V to 3.6V I/O range.
13 1B1 bidirectional Input/output 1B1 referenced to VCCB, operating over a 0.65V to 3.6V I/O range.
14 2OE input Three-state output enable for port 2, referenced to VCCA; driving it high places the port 2 outputs in the high-impedance state.
15 1OE input Three-state output enable for port 1, referenced to VCCA; driving it high places the port 1 outputs in the high-impedance state.
16 VCCB power_in B-port supply voltage, specified for 0.65V ≤ VCCB ≤ 3.6V; the B port tracks VCCB.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
