74AHCV244A Octal buffer/line driver 3-state Rev. 2 21 March 2018 Product data sheet 1 General description The 74AHCV244A is an 8-bit buffer/line driver with 3-state outputs and Schmitt trigger inputs. The device features two output enables (1OE and 2OE). A HIGH on nOE causes the associated outputs to assume a high-impedance OFF-state. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments. The data (nAn) and control (nOE) inputs include Schmitt trigger inputs, capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. This device is fully specified for partial Power-down applications using I . The I OFF OFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down. 2 Features and benefits Wide supply voltage range from 1.8 V to 5.5 V Typical t of 3.0 ns at 5 V pd Typical V < 0.8 V at V = 3.3 V, T = 25 C OL(p) CC amb Typical V > 2.3 V at V = 3.3 V, T = 25 C OH(v) CC amb Supports mixed-mode voltage operation on all ports I circuitry provides partial Power-down mode operation OFF Latch-up performance exceeds 250 mA per JESD 78 Class II ESD protection: HBM ANSI/ESDA/JEDEC JS-001 Class 2 exceeds 3 kV MM JESD22-A115-A exceeds 150 V CDM JESD22-C101E exceeds 2 kV Specified from -40 C to +85 C and from -40 C to +125 C 3 Ordering information Table 1.Ordering information Type number Package Temperature range Name Description Version 74AHCV244APW -40 C to +125 C TSSOP20 plastic thin shrink small outline package 20 leads SOT360-1 body width 4.4 mmNexperia 74AHCV244A Octal buffer/line driver 3-state 4 Functional diagram 1A0 1Y0 2 18 1A1 1Y1 4 16 1A2 1Y2 6 14 1A3 1Y3 8 12 1 EN 1OE 1 18 2 2A0 2Y0 17 3 4 16 6 14 2A1 2Y1 15 5 12 8 2A2 2Y2 13 7 19 EN 2A3 2Y3 9 11 11 9 7 13 2OE 19 5 15 3 17 aaa-025792 mna873 Figure 1.Logic symbol Figure 2.IEC logic symbol 5 Pinning information 5.1 Pinning 74AHCV244A 1OE 1 20 V CC 1A0 2 19 2OE 2Y0 3 18 1Y0 1A1 4 17 2A0 2Y1 5 16 1Y1 1A2 6 15 2A1 2Y2 7 14 1Y2 1A3 8 13 2A2 2Y3 9 12 1Y3 GND 10 11 2A3 aaa-025793 Figure 3.Pin configuration SOT360-1 (TSSOP20) 74AHCV244A All information provided in this document is subject to legal disclaimers.
