TC7MH157FK TC7MH157FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MH157FK TC7MH157FK Quad 2-Channel Multiplexer The TC7MH157FK TC7MH157FK is an advanced high speed CMOS quad 2-channel multiplexer fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent bipolar schottky TTL while maintaining the CMOS low power dissipation. It consists of four 2-input digital multiplexers with common select and strobe inputs. When the strobe input (ST) is held "H" level, selection of data is inhibited and all the outputs become "L" level. The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs. Weight: 0.02 g (typ.) An Input protection circuit ensures that 0 to 7 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and on two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages. Features · High speed: tpd = 4.1 ns (typ.) (VCC = 5 V) · Low power dissipation: ICC = 4 µA (max) (Ta = 25°C) · High noise immunity: VNIH = VNIL = 28% VCC (min) · Power down protection is provided on all inputs. · Balanced propagation delays: tpLH tpHL · Wide operating voltage range: VCC (opr) = 2~5.5 V · Low noise: VOLP = 0.8 V (max) · Pin and function compatible with 74ALS157 74ALS157 1 2001-09-12 TC7MH157FK TC7MH157FK Pin Assignment (top view) SELECT 1 1A 2 1B 3 1Y IEC Logic Symbol ST 16 VCC A S G 15 ST SELECT B A 14 4A 4 Y B 13 4B 2A 5 A Y 12 4Y 2B 6 B A 11 3A 2Y 7 Y Y B 10 3B 1A 1B 2A 2B 3A 3B 4A 4B GND 8 9 (15) EN 3Y (1) (2) (3) (5) (6) (11) (10) (14) (13) G1 1 1 MUX (4) (7) (9) (12) 1Y 2Y 3Y 4Y Truth Table Inputs Outputs ST Select A B H X X X L L L L X L L L H X H L H X L L L H X H H X: Don't care 2 2001-09-12 TC7MH157FK TC7MH157FK System Diagram 1A 1B 2A 2B 3A 3B 4A 4B SELECT 2 3 fA fB 4 1Y fA fB 7 2Y fA fB 9 3Y fA fB 12 4Y 5 6 11 10 14 13 1 fA fB ST 15 Maximum Ratings Characteristics Symbol Rating Unit Supply voltage range VCC -0.5~7.0 V DC input voltage VIN -0.5~7.0 V DC output voltage VOUT -0.5~VCC + 0.5 V Input diode current IIK -20 mA Output diode current IOK ±20 mA DC output current IOUT ±25 mA DC VCC/ground current ICC ±50 mA Power dissipation PD 180 mW Storage temperature Tstg -65~150 °C 3 2001-09-12 TC7MH157FK TC7MH157FK Recommended Operating Conditions Characteristics Symbol Rating Unit Supply voltage VCC 2.0~5.5 V Input voltage VIN 0~5.5 V VOUT 0~VCC V -40~85 °C Output voltage Operating temperature Topr Input rise and fall time 0~100 (VCC = 3.3 ± 0.3 V) dt/dv 0~20 (VCC = 5 ± 0.5 V) ns/V Electrical Characteristics DC Characteristics Characteristics Symbol Ta = 25°C Test Condition Ta = -40~85°C VCC (V) Typ.
